parse_blob() has never actually been used; it has served simply to
avoid having a confusing gap in the API. Instead of leaving it, put in
a comment that explains what "parsing a blob" entails (making sure the
object is actually readable), and why code might care whether a blob
has been parsed or not.

Internally "git grep" runs regexec(3) that expects its input string
to be NUL terminated. When searching inside blob data, read_sha1_file()
automatically gives such a buffer, but builtin-grep.c forgot to put
the NUL at the end, even though it allocated enough space for it.

This makes "subtree" more orthogonal to the rest of recursive merge, so
that you can use subtree and ours/theirs features at the same time. For
example, you can now say:
git merge -s subtree -Xtheirs other
to merge with "other" branch while shifting it up or down to match the
shape of the tree of the current branch, and resolving conflicts favoring
the changes "other" branch made over changes made in the current branch.
It also allows the prefix used to shift the trees to be specified using
the "-Xsubtree=$prefix" option. Giving an empty prefix tells the command
to figure out how much to shift trees automatically as we have always
done. "merge -s subtree" is the same as "merge -s recursive -Xsubtree="
(or "merge -s recursive -Xsubtree").
Based on an old patch done back in the days when git-merge was a script;
Avery ported the script part to builtin-merge.c. Bugs in shift_tree()
is mine.

To implement gettimeofday(), a broken-down UTC time was requested from the
system using GetSystemTime(), then tm_to_time_t() was used to convert it
to a time_t because it does not look at the current timezone, which
mktime() would do.
Use GetSystemTimeAsFileTime() and a different conversion path to avoid this
back-reference from the compatibility layer to the generic code.

It allows to remove Pthreads for Win32 dependency for MSVC, msysgit and
Cygwin.
[J6t: If the MinGW build was built as part of the msysgit build
environment, then threading was already enabled because the
pthreads-win32 package is available in msysgit. With this patch, we can now

In particular, the following warning is issued while compiling
compat/msvc.c:
...mingw.c(223) : warning C4133: 'function' : incompatible \
types - from '_stati64 *' to '_stat64 *'
which relates to a call of _fstati64() in the mingw_fstat()
function definition.
This is caused by various layers of macro magic and attempts to
avoid macro redefinition compiler warnings. For example, the call
to _fstati64() mentioned above is actually a call to _fstat64(),
and expects a pointer to a struct _stat64 rather than the struct
_stati64 which is passed to mingw_fstat().
The definition of struct _stati64 given in compat/msvc.h had the
same "shape" as the definition of struct _stat64, so the call to
_fstat64() does not actually cause any runtime errors, but the
structure types are indeed incompatible.
In order to avoid the compiler warning, we add declarations for the
mingw_lstat() and mingw_fstat() functions and supporting macros to
msvc.h, suppressing the corresponding declarations in mingw.h, so
that we can use the appropriate structure type (and function) names
from the msvc headers.

When stdin, stdout, or stderr must be redirected for a child process that
on Windows is spawned using one of the spawn() functions of Microsoft's
C runtime, then there is no choice other than to
1. make a backup copy of fd 0,1,2 with dup
2. dup2 the redirection source fd into 0,1,2
3. spawn
4. dup2 the backup back into 0,1,2
5. close the backup copy and the redirection source
We used this idiom as well -- but we are not using the spawn() functions
anymore!
Instead, we have our own implementation. We had hardcoded that stdin,
stdout, and stderr of the child process were inherited from the parent's
fds 0, 1, and 2. But we can actually specify any fd.
With this patch, the fds to inherit are passed from start_command()'s
WIN32 section to our spawn implementation. This way, we can avoid the
backup copies of the fds.
The backup copies were a bug waiting to surface: The OS handles underlying
the dup()ed fds were inherited by the child process (but were not
associated with a file descriptor in the child). Consequently, the file or
pipe represented by the OS handle remained open even after the backup copy
was closed in the parent process until the child exited.
Since our implementation of pipe() creates non-inheritable OS handles, we
still dup() file descriptors in start_command() because dup() happens to
create inheritable duplicates. (A nice side effect is that the fd cleanup
in start_command is the same for Windows and Unix and remains unchanged.)

Our implementation of pipe() must create non-inheritable handles for the
reason that when a child process is started, there is no opportunity to
close the unneeded pipe ends in the child (on POSIX this is done between
fork() and exec()).
Previously, we used the _pipe() function provided by Microsoft's C runtime
(which creates inheritable handles) and then turned the handles into
non-inheritable handles using the DuplicateHandle() API.
Simplify the procedure by using the CreatePipe() API, which can create
non-inheritable handles right from the beginning.
