Add the ability to create blob given a provider of chunks of bytes

Fix compilation warning and failing test

git_status_file returns GIT_ENOTFOUND for "域名检测工具.exe" (and similarly named files) 

git_status_file would always return GIT_ENOTFOUND for these files.

The underlying bug was that git__strcmp_cb, which is used by
git_path_with_stat_cmp to sort entries in the working directory,
compares strings based on unsigned chars (this is confirmed by the
strcmp(3) manpage), while git__prefixcmp, which is used by
workdir_iterator__entry_cmp to search for a path in the working
directory, compares strings based on char. So the sort puts this path at
the end of the list, while the search expects it to be at the beginning.

The fix was simply to make git__prefixcmp compare using unsigned chars,
just like strcmp(3). The rest of the change is just adding/updating
tests.

Fix git_remote_connected

Fix checking for the presence of a flag

Enable mingw cross-compilation in travis-ci

Two things:
1) By default, Linux CMake puts -fPIC on the link line. So we remove that
for MINGW to avoid warnings that it will be ignored.
2) Similarly, move -fvisibility=hidden flag to be for non-mingw
compilation only to avoid warnings that it will be ignored.

Otherwise we can't cross-compile on Linux.

Sometimes it's useful not to perform the check. Allow it to be
configurable.

tests-clar/core: fix non-null warning

gcc 4.7.0 apparently doesn't see that we won't call setenv with NULL as
second argument.
