Make hideRefs handling in upload-pack consistent with the behavior
described in the documentation by stripping refs before comparing them
with prefixes in hideRefs.

Right now, there is no clear definition of how transfer.hideRefs should
behave when a namespace is set. Explain that hideRefs prefixes match
stripped names in that case. This is how hideRefs patterns are currently
handled in receive-pack.

The name-hash subsystem that is used to cope with case insensitive
filesystems keeps track of directories and their on-filesystem
cases for all the paths in the index by holding a pointer to a
randomly chosen cache entry that is inside the directory (for its
ce->ce_name component). This pointer was not updated even when the
cache entry was removed from the index, leading to use after free.
This was fixed by recording the path for each directory instead of
borrowing cache entries and restructuring the API somewhat.

Call child_process_clear() when a child ends to release the memory
allocated for its environment. This is necessary because unlike all
other users of start_command() we don't call finish_command(), which
would have taken care of that for us.
This leak was introduced by f063d38b (daemon: use cld->env_array
when re-spawning).

git_mailinfo_config() expects "struct mailinfo *". But in
setup_mailinfo(), "mi" is already "struct mailinfo *". &mi would make
it "struct mailinfo **" and git_mailinfo_config() would damage some
other memory when it assigns some value to mi->use_scissors.
This is caught by t4150.20. git_mailinfo_config() breaks
mi->name.alloc and makes strbuf_release() in clear_mailinfo() attempt
to free strbuf_slopbuf.

If we're on a detached HEAD then wt_shortstatus_print_tracking() takes
the string "HEAD (no branch)", translates it, skips the first eleven
characters and passes the result to branch_get(), which returns a bogus
result and accesses memory out of bounds in order to produce it.
Somehow stat_tracking_info(), which is passed that result, does the
right thing anyway, i.e. it finds that there is no base.
Avoid the bogus results and memory accesses by checking for HEAD first
and exiting early in that case. This fixes t7060 with --valgrind.

Reverse blame can be used to locate removal of lines which does not
change adjacent lines. Such edits do not appear in non-reverse blame,
because the adjacent lines last changed commit is older history, before
the edit.
For a big and active project which uses topic branches, or analogous
feature, for example pull-requests, the history can contain many
concurrent branches, and even after an edit merged into the target
branch, there are still many (sometimes several tens or even hundreds)
topic branch which do not contain it:
a0--a1-----*a2-*a3-a4...-*a100
|\ / / /
| b0-B1..bN / /
|\ / /
| c0.. ..cN /
\ /
z0.. ..zN
Here, the '*'s mark the first parent in merge, and uppercase B1 - the
commit where the line being blamed for was removed. Since commits cN-zN
do not contain B1, they still have the line removed in B1, and
reverse blame can report that the last commit for the line was zN
(meaning that it was removed in a100). In fact it really does return
some very late commit, and this makes it unusable for finding the B1
commit.
The search could be done by blame --reverse --first-parent. For range
a0..a100 it would return a1, and then only one additional blame along
the a0..bN will return the desired commit b0. But combining --reverse
and --first-parent was forbidden in 95a4fb0eac, because incorrectly
specified range could produce unexpected and meaningless result.
Add test which describes the expected behavior of
`blame --reverse --first-parent` in the case described above.

In ref-filter.c the comparison of refs while sorting is handled by
cmp_ref_sorting() function. When sorting as per numerical values
(e.g. --sort=objectsize) there is no fallback comparison when both
refs hold the same value. This can cause unexpected results (i.e. the
order of listing refs with equal values cannot be pre-determined) as
pointed out by Johannes Sixt ($gmane/280117).
Hence, fallback to alphabetical comparison based on the refname
whenever the other criterion is equal.
A test in t3203 was expecting that branch-two sorts before HEAD, which
happened to be how qsort(3) on Linux sorted the array, but (1) that
outcome was not even guaranteed, and (2) once we start breaking ties
with the refname, "HEAD" should sort before "branch-two" so the
original expectation was inconsistent with the criterion we now use.
Update it to match the new world order, which we can now depend on
being stable.
