Not all OSes use st_ctim and st_mtim in their struct stat. In
particular, it appears that OS X uses st_*timespec instead. So add a
Makefile variable and #define called USE_ST_TIMESPEC to switch the
USE_NSEC defines to use st_*timespec.
This also turns it on by default for OS X (Darwin) machines. Likely
this is a sane default for other BSD kernels as well, but I don't have
any to test that assumption on.

Traditionally, the lack of USE_NSEC meant "do not record nor use the
nanosecond resolution part of the file timestamps". To avoid problems on
filesystems that lose the ns part when the metadata is flushed to the disk
and then later read back in, disabling USE_NSEC has been a good idea in
general.
If you are on a filesystem without such an issue, it does not hurt to read
and store them in the cached stat data in the index entries even if your
git is compiled without USE_NSEC. The index left with such a version of
git can be read by git compiled with USE_NSEC and it can make use of the
nanosecond part to optimize the check to see if the path on the filesystem
hsa been modified since we last looked at.

The installation rules wanted to differentiate between a template_dir that
is given as an absolute path (e.g. /usr/share/git-core/templates) and a
relative one (e.g. share/git-core/templates) but it was done by checking
if $(abspath $(template_dir)) and $(template_dir) yield the same string.
This was wrong in at least two ways.
* The user can give template_dir with a trailing slash from the command
line to invoke make or from the included config.mak. A directory path
ought to mean the same thing with or without such a trailing slash but
use of $(abspath) means an absolute path with a trailing slash fails
the test.
* Versions of GNU make older than 3.81 do not have $(abspath) to begin
with.
This changes the detection logic to see if the given path begins with a
slash.

This commit adds support for relocatable binaries (called
RUNTIME_PREFIX). Such binaries can be moved together with the
system configuration files to a different directory, as long as the
relative paths from the binary to the configuration files is
preserved. This functionality is essential on Windows where we
deliver git binaries with an installer that allows to freely choose
the installation location.
If RUNTIME_PREFIX is unset we use the static prefix. This will be
the default on Unix. Thus, the behavior on Unix will remain
identical to the old implementation, which used to add the prefix
in the Makefile.
If RUNTIME_PREFIX is set the prefix is computed from the location
of the executable. In this case, system_path() tries to strip
known directories that executables can be located in from the path
of the executable. If the path is successfully stripped it is used
as the prefix. For example, if the executable is
"/msysgit/bin/git" and BINDIR is "bin", then the prefix computed is
"/msysgit".
If the runtime prefix computation fails, we fall back to the static
prefix specified in the makefile. This can be the case if the
executable is not installed at a known location. Note that our
test system sets GIT_CONFIG_NOSYSTEM to tell git to ignore global
configuration files during testing. Hence testing does not trigger
the fall back.
Note that RUNTIME_PREFIX only works on Windows, though adding
support on Unix should not be too hard. The implementation
requires argv0_path to be set to an absolute path. argv0_path must
point to the directory of the executable. We use assert() to
verify this in debug builds. On Windows, the wrapper for main()
(see compat/mingw.h) guarantees that argv0_path is correctly
initialized. On Unix, further work is required before
RUNTIME_PREFIX can be enabled.

for RUNTIME_PREFIX)
This commit prepares the Makefile for relocatable binaries (called
RUNTIME_PREFIX). Such binaries will be able to be moved together
with the system configuration files to a different directory,
requiring to compute the prefix at runtime.
In a first step, we make all paths relative in the Makefile and
teach system_path() to add the prefix instead. We used to compute
absolute paths in the Makefile and passed them to C as defines. We
now pass relative paths to C and call system_path() to add the
prefix at runtime.

If a piece of code wanted to do some cleanup before exiting
(e.g., cleaning up a lockfile or a tempfile), our usual
strategy was to install a signal handler that did something
like this:
do_cleanup(); /* actual work */
signal(signo, SIG_DFL); /* restore previous behavior */
raise(signo); /* deliver signal, killing ourselves */
For a single handler, this works fine. However, if we want
to clean up two _different_ things, we run into a problem.
The most recently installed handler will run, but when it
removes itself as a handler, it doesn't put back the first
handler.
This patch introduces sigchain, a tiny library for handling
a stack of signal handlers. You sigchain_push each handler,
and use sigchain_pop to restore whoever was before you in
the stack.

The install target uses a foreach loop to generate a single long shell
command line to handle installation of the built-in git commands. The
maximum length of the argument list varies by platform, and this use of
foreach quickly grows the length of the argument list. Current git can
exceed the default maximum argument list length on IRIX 6.5 of 20480
depending on the installation path.
Rather than using make's foreach loop to pre-generate the shell command
line, use a shell for-loop and allow the shell to iterate through each of
the built-in commands.

Manipulating the character class table in ctype.c by hand is error prone.
To ensure that typos are found quickly, add a test program and script.
test-ctype checks the output of the character class macros isspace() et.
al. by applying them on all possible char values and consulting a list of
all characters in the particular class. It doesn't check tolower() and
toupper(); this could be added later.

Commit notes are blobs which are shown together with the commit
message. These blobs are taken from the notes ref, which you can
configure by the config variable core.notesRef, which in turn can
be overridden by the environment variable GIT_NOTES_REF.
The notes ref is a branch which contains "files" whose names are
the names of the corresponding commits (i.e. the SHA-1).
The rationale for putting this information into a ref is this: we
want to be able to fetch and possibly union-merge the notes,
maybe even look at the date when a note was introduced, and we
want to store them efficiently together with the other objects.

Earlier the plan was to eventually eradicate git-foo executables from the
filesystem for all the built-in commands, but when we released 1.6.0 we
decided not to do so. Instead, it has been promised that by prepending
the output from $(git --exec-path) to your $PATH, you can keep using the
dashed form of commands.
This also allows "git stage" to appear in the autogenerated command list,
which is used to offer man pages by "git help" command.

This can do the lstat() storm in parallel, giving potentially much
improved performance for cold-cache cases or things like NFS that have
weak metadata caching.
Just use "read_cache_preload()" instead of "read_cache()" to force an
optimistic preload of the index stat data. The function takes a
pathspec as its argument, allowing us to preload only the relevant
portion of the index.

Both sets of code assume that one specifies a diff profile
as a gitattribute via the "diff=foo" attribute. They then
pull information about that profile from the config as
diff.foo.*.
The code for each is currently completely separate from the
other, which has several disadvantages:
- there is duplication as we maintain code to create and
search the separate lists of external drivers and
funcname patterns
- it is difficult to add new profile options, since it is
unclear where they should go
- the code is difficult to follow, as we rely on the
"check if this file is binary" code to find the funcname
pattern as a side effect. This is the first step in
refactoring the binary-checking code.
This patch factors out these diff profiles into "userdiff"
drivers. A file with "diff=foo" uses the "foo" driver, which
is specified by a single struct.
Note that one major difference between the two pieces of
code is that the funcname patterns are always loaded,
whereas external drivers are loaded only for the "git diff"
porcelain; the new code takes care to retain that situation.

This breaks my build on Solaris 8, as there is no separate
libiconv.
The history of this line is somewhat convoluted. In 2fd955c
(in November 2005), NEEDS_LIBICONV was turned on for all
Solaris builds, claiming to "fix an error in Solaris 10 by
setting NEEDS_LIBICONV".
Later, e15f545 (in February of 2006) claimed that "Solaris
9+ don't need iconv", and moved NEEDS_LIBICONV into a
section for Solaris 8.
Furthermore, Brandon Casey claims in
<5A1KxlhmUIHe8iXPxnXYuNXsq0Yjlbwkz2eBin3z7ELuL9nK-4tSpw@cipher.nrlssc.navy.mil>
that he does not set NEEDS_LIBICONV for Solaris 7.
So either one of those commits is totally wrong, or there is
some other magic going on where some Solaris installs need
it and others don't.
Given Brandon's statement and my problems on Solaris 8 with
NEEDS_LIBICONV, I am inclined to think the first commit was
bogus, and that NEEDS_LIBICONV shouldn't be set for Solaris
at all by default. If somebody wants to use iconv and has
installed it manually, they can set it in their config.mak.

lstat/stat functions in Cygwin are very slow, because they try to emulate
some *nix things that Git does not actually need. This patch adds Win32
specific implementation of these functions for Cygwin.
This implementation handles most situation directly but in some rare cases
it falls back on the implementation provided for Cygwin. This is necessary
for two reasons:
- Cygwin has its own file hierarchy, so absolute paths used in Cygwin is
not suitable to be used Win32 API. cygwin_conv_to_win32_path can not be
used because it automatically dereference Cygwin symbol links, also it
causes extra syscall. Fortunately Git rarely use absolute paths, so we
always use Cygwin implementation for absolute paths.
- Support of symbol links. Cygwin stores symbol links as ordinary using
one of two possible formats. Therefore, the fast implementation falls
back to Cygwin functions if it detects potential use of symbol links.
The speed of this implementation should be the same as mingw_lstat for
common cases, but it is considerable slower when the specified file name
does not exist.
Despite all efforts to make the fast implementation as robust as possible,
it may not work well for some very rare situations. I am aware only one
situation: use Cygwin mount to bind unrelated paths inside repository
together. Therefore, the core.ignoreCygwinFSTricks configuration option is
provided, which controls whether native or Cygwin version of stat is used.
