dc6373b034 git bundle create <bundle> leaks handle the revlist is empty.
issue #790: git bundle create does not close handle to *.lock file

This problem happens when an user tries to create an empty bundle, using the
following command:  `git bundle create <bundle> <revlist>` and when <revlist>
resolve to an empty list (for example, like `master..master`), `git bundle` fails
and warn the user about how it don't want to create empty bundle.

In that case, git tries to delete the `<bundle>.lock` file, and since there's still
an open file handle, fails to do so and ask the user if it should retry (which will
fail again).

The lock can still be deleted manually by the user (and it is required if the user
want to create a bundle after revising his rev-list).

00c822c583 gc/repack: release packs when needed
On Windows, files cannot be removed nor renamed if there are still
handles held by a process. To remedy that, we introduced the
close_all_packs() function.

Earlier, we made sure that the packs are released just before `git gc`
is spawned, in case that gc wants to remove no-longer needed packs.

But this developer forgot that gc itself also needs to let go of packs,
e.g. when consolidating all packs via the --aggressive option.

Likewise, `git repack -d` wants to delete obsolete packs and therefore
needs to close all pack handles, too.

69ca969cb8 mingw: support spawning programs containing spaces in their names
The CreateProcessW() function does not really support spaces in its
first argument, lpApplicationName. But it supports passing NULL as
lpApplicationName, which makes it figure out the application from the
(possibly quoted) first argument of lpCommandLine.

Let's use that trick (if we are certain that the first argument matches
the executable's path) to support launching programs whose path contains
spaces.

48a9db9b32 Merge 'aslr' into HEAD
Address Space Layout Randomization (ASLR) allows executables' memory
layout to change at random between runs, and therefore offers a quite
decent protection against many attacks.

We enable ASLR because MSYS2's C compiler offers support for ASLR, and
whatever performance impact it has is neglible, according to
https://insights.sei.cmu.edu/cert/2014/02/differences-between-aslr-on-windows-and-linux.html

8741d85eaa Do not mask the username when reading credentials
When user is asked for credentials there is no need to mask username,
so PROMPT_ASKPASS flag on calling credential_ask_one for login is
unnecessary.

credential_ask_one internally uses git_prompt which in case of given
flag PROMPT_ASKPASS uses masked input method instead of
git_terminal_prompt, which does not mask user input.

This fixes #675

2f3510dc7b git gui: fix staging a second line to a 1-line file
When a 1-line file is augmented by a second line, and the user tries to
stage that single line via the "Stage Line" context menu item, we do not
want to see "apply: corrupt patch at line 5".

The reason for this error was that the hunk header looks like this:

	@@ -1 +1,2 @@

but the existing code expects the original range always to contain a
comma. This problem is easily fixed by cutting the string "1 +1,2"
(that Git GUI formerly mistook for the starting line) at the space.

07dc841ed9 Enable DEP and ASLR
Enable DEP (Data Execution Prevention) and ASLR (Address Space Layout
Randomization) support. This applies to both 32bit and 64bit builds
and makes it substantially harder to exploit security holes in Git by
offering a much more unpredictable attack surface.

ASLR interferes with GDB's ability to set breakpoints. A similar issue
holds true when compiling with -O2 (in which case single-stepping is
messed up because GDB cannot map the code back to the original source
code properly). Therefore we simply enable ASLR only when an
optimization flag is present in the CFLAGS, using it as an indicator
that the developer does not want to debug in GDB anyway.

3c4531e481 Don't let ld strip relocations
This is the first step for enabling ASLR (Address Space Layout
Randomization) support. We want to enable ASLR for better protection
against exploiting security holes in Git.

The problem fixed by this commit is that `ld.exe` seems to be stripping
relocations which in turn will break ASLR support. We just make sure
it's not stripping the main executable entry.

639187ae29 engine.pl: ignore invalidcontinue.obj which is known to MSVC
Commit 4b623d8 (MSVC: link in invalidcontinue.obj for better
POSIX compatibility, 2014-03-29) introduced invalidcontinue.obj
into the Makefile output, which was not parsed correctly by the
buildsystem. Ignore it, as it is known to Visual Studio and,
there is no matching source file.

Only substitute filenames ending with .o when generating the
source .c filename, otherwise a .cbj file may be expected.

Split the .o and .obj processing; 'make' does not produce .obj
files.

In the future there may be source files that produce .obj files
so keep the two issues (.obj files with & without source files)
separate.

b3ec5f9e1c t7800: fix quoting
When passing a command-line to call an external diff command to the
difftool, we must be prepared for paths containing special characters,
e.g. backslashes in the temporary directory's path on Windows.

This has been caught by running the test suite with an MSVC-built Git:
in contrast to the MINGW one, it does not rewrite `$TMP` to use forward
slashes instead of backslashes.

6e299b28cc msvc: work around iconv() not setting errno
When compiling with MSVC, we rely on NuPkgs to provide the binaries of
dependencies such as libiconv. The libiconv 1.14.0.11 package available
from https://www.nuget.org/packages/libiconv seems to have a bug where
it does not set errno (when we would expect it to be E2BIG).

Let's simulate the error condition by taking less than 16 bytes
remaining in the out buffer as an indicator that we ran out of space.
While 16 might seem a bit excessive (when converting from, say, any
encoding to UTF-8, 8 bytes should be fine), it is designed to be a safe
margin.
