e4ec5b4969 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

bf6a19f53e mingw: respect core.hidedotfiles = false in git-init again
This is a brown paper bag. When adding the tests, we actually failed
to verify that the config variable is heeded in git-init at all. And
when changing the original patch that marked the .git/ directory as
hidden after reading the config, it was lost on this developer that
the new code would use the hide_dotfiles variable before the config
was read.

The fix is obvious: read the (limited, pre-init) config *before*
creating the .git/ directory.

9d91560b5f status: carry the --no-lock-index option for backwards-compatibility
When a third-party tool periodically runs `git status` in order to keep
track of the state of the working tree, it is a bad idea to lock the
index: it might interfere with interactive commands executed by the
user, e.g. when the user wants to commit files.

Git for Windows introduced the `--no-lock-index` option a long time ago
to fix that (it made it into Git for Windows v2.9.2(3)) by simply
avoiding to write that file.

The downside is that the periodic `git status` calls will be a little
bit more wasteful because they may have to refresh the index repeatedly,
only to throw away the updates when it exits. This cannot really be
helped, though, as tools wanting to get a periodic update of the status
have no way to predict when the user may want to lock the index herself.

Sadly, a competing approach was submitted (by somebody who apparently
has less work on their plate than this maintainer) that made it into
v2.15.0 but is *different*: instead of a `git status`-only option, it is
an option that comes *before* the Git command and is called differently,
too.

Let's give previous users a chance to upgrade to newer Git for Windows
versions by handling the `--no-lock-index` option, still, though with a
big fat warning.

afbbab6962 bundle: refuse to create empty bundle
When an user tries to create an empty bundle via `git bundle create
<bundle> <revlist>` where <revlist> resolves to an empty list (for
example, like `master..master`), the command fails and warns the user
about how it don't want to create empty bundle.

However, on Windows the .lock file was still open and could not be
deleted properly. This patch fixes that issue.

b91bbe4905 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.

b600965324 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.

1151cb9824 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

b4f601fb3b t7300: git clean -dfx must show an error with long paths
In particular on Windows, where the default maximum path length is quite
small, but there are ways to circumvent that limit in many cases, it is
very important that users be given an indication why their command
failed because of too long paths when it did.

This test case makes sure that a warning is issued that would have
helped the user who reported Git for Windows' issue 521:

fb5896eae8 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.

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.

def980d901 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.

ad73ef0e8a 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,

in contrast to the MINGW one, it does not rewrite `$TMP` to use forward
slashes instead of backslashes.

8a347cb9e8 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.
