In the spirit of v1.6.4-rc0~124 (MinGW: Fix compiler warning in
merge-recursive, 2009-05-23), use a 32-bit integer instead; the
dump file parser does not support any better, anyway.

dirent is #define’d to mingw_dirent in compat/mingw.h, with the
result that
obj_pool_gen(dirent, struct repo_dirent, 4096)
creates functions with names like mingw_dirent_alloc and
references to dirent_alloc go unresolved. Rename the functions
to dent_* to avoid this problem.

svndump parses data that is in SVN dumpfile format produced by
`svnadmin dump` with the help of line_buffer and uses repo_tree and
fast_export to emit a git fast-import stream.
Based roughly on com.hydrografix.svndump 0.92 from the SvnToCCase
project at <http://svn2cc.sarovar.org/>, by Stefan Hegny and
others.
[rr: allow input from files other than stdin]
[jn: with test, more error reporting]

repo_tree maintains the exporter's state and provides a facility to to
call fast_export, which writes objects to stdout suitable for
consumption by fast-import.
The exported functions roughly correspond to Subversion FS operations.
. repo_add, repo_modify, repo_copy, repo_replace, and repo_delete
update the current commit, based roughly on the corresponding
Subversion FS operation.
. repo_commit calls out to fast_export to write the current commit to
the fast-import stream in stdout.
. repo_diff is used by the fast_export module to write the changes
for a commit.
. repo_reset erases the exporter's state, so valgrind can be happy.
[rr: squelched compiler warnings]
[jn: removed support for maintaining state on-disk, though we may
want to add it back later]

This library provides thread-unsafe fgets()- and fread()-like
functions where the caller does not have to supply a buffer. It
maintains a couple of static buffers and provides an API to use
them.

Intern strings so they can be compared by address and stored without
wasting space.
This library uses the macros in the obj_pool.h and trp.h to create a
memory pool for strings and expose an API for handling them.

[jn: with some API simplifications, new documentation and tests]

Provide macros to generate a type-specific treap implementation and
various functions to operate on it. It uses obj_pool.h to store memory
nodes in a treap. Previously committed nodes are never removed from
the pool; after any *_commit operation, it is assumed (correctly, in
the case of svn-fast-export) that someone else must care about them.
Treaps provide a memory-efficient binary search tree structure.
Insertion/deletion/search are about as about as fast in the average
case as red-black trees and the chances of worst-case behavior are
vanishingly small, thanks to (pseudo-)randomness. The bad worst-case
behavior is a small price to pay, given that treaps are much simpler
to implement.

Add a memory pool library implemented using C macros. The
obj_pool_gen() macro creates a type-specific memory pool.
The memory pool library is distinguished from the existing specialized
allocators in alloc.c by using a contiguous block for all allocations.
This means that on one hand, long-lived pointers have to be written as
offsets, since the base address changes as the pool grows, but on the
other hand, the entire pool can be easily written to the file system.
This could allow the memory pool to persist between runs of an
application.
For the svn importer, such a facility is useful because each svn
revision can copy trees and files from any previous revision. The
relevant information for all revisions has to persist somehow to
support incremental runs.
[rr: minor cleanups]
[jn: added tests; removed file system backing for now]

Teach the build system to build a separate library for the
upcoming subversion interop support.
The resulting vcs-svn/lib.a does not contain any code, nor is
it built during a normal build. This is just scaffolding for
later changes.
