6a7f363170 rename_tmp_log(): use raceproof_create_file()
Besides shortening the code, this saves an unnecessary call to
safe_create_leading_directories_const() in almost all cases.

177978f56a raceproof_create_file(): new function
Add a function that tries to create a file and any containing
directories in a way that is robust against races with other processes
that might be cleaning up empty directories at the same time.

The actual file creation is done by a callback function, which, if it
fails, should set errno to EISDIR or ENOENT according to the convention
of open(). raceproof_create_file() detects such failures, and
respectively either tries to delete empty directories that might be in
the way of the file or tries to create the containing directories. Then
it retries the callback function.

This function is not yet used.

15ee2c72e7 refname_is_safe(): correct docstring
The behavior of refname_is_safe() was changed in

    e40f355 "refname_is_safe(): insist that the refname already be normalized", 2016-04-27

without a corresponding update to its docstring. The function is in fact
stricter than documented, because it now insists that the result of
normalizing the part of a refname following "refs/" is identical to that
part of the original refname. Fix the docstring.

a9b8a09c3c mingw: replace isatty() hack
Git for Windows has carried a patch that depended on internals
of MSVC runtime, but it does not work correctly with recent MSVC
runtime. A replacement was written originally for compiling
with VC++. The patch in this message is a backport of that
replacement, and it also fixes the previous attempt to make
isatty() tell that /dev/null is *not* an interactive terminal.

86924838e3 mingw: fix colourization on Cygwin pseudo terminals
Git only colours the output and uses pagination if isatty() returns 1.
MSYS2 and Cygwin emulate pseudo terminals via named pipes, meaning that
isatty() returns 0.

f7f90e0f4f (mingw: make isatty() recognize MSYS2's pseudo terminals
(/dev/pty*), 2016-04-27) fixed this for MSYS2 terminals, but not for
Cygwin.

The named pipes that Cygwin and MSYS2 use are very similar. MSYS2 PTY pipes
are called 'msys-*-pty*' and Cygwin uses 'cygwin-*-pty*'. This commit
modifies the existing check to allow both MSYS2 and Cygwin PTY pipes to be
identified as TTYs.

Note that pagination is still broken when running Git for Windows from
within Cygwin, as MSYS2's less.exe is spawned (and does not like to
interact with Cygwin's PTY).

This partially fixes https://github.com/git-for-windows/git/issues/267

fee807c5f6 mingw: adjust is_console() to work with stdin
When determining whether a handle corresponds to a *real* Win32 Console
(as opposed to, say, a character device such as /dev/null), we use the
GetConsoleOutputBufferInfo() function as a tell-tale.

However, that does not work for *input* handles associated with a
console. Let's just use the GetConsoleMode() function for input handles,
and since it does not work on output handles fall back to the previous
method for those.

This patch prepares for using is_console() instead of my previous
misguided attempt in cbb3f3c9b1 (mingw: intercept isatty() to handle
/dev/null as Git expects it, 2016-12-11) that broke everything on
Windows.

08414938a2 mailinfo.c: move side-effects outside of assert
Since 6b4b013f18 (mailinfo: handle in-body header continuations,
2016-09-20, v2.11.0) mailinfo.c has contained new code with an
assert of the form:

	assert(call_a_function(...))

The function in question, check_header, has side effects.  This
means that when NDEBUG is defined during a release build the
function call is omitted entirely, the side effects do not
take place and tests (fortunately) start failing.

Since the only time that mi->inbody_header_accum is appended to is
in check_inbody_header, and appending onto a blank
mi->inbody_header_accum always happens when is_inbody_header is
true, this guarantees a prefix that causes check_header to always
return true.

Therefore replace the assert with an if !check_header + DIE
combination to reflect this.
