[PATCH 0/11] Miscellaneous MinGW port fallout

This is a series of smallish, unrelated changes that were necessary for the MinGW port.

[PATCH 01/11] t5300-pack-object.sh: Split the big verify-pack test into
	smaller parts.
[PATCH 02/11] t7501-commit.sh: Not all seds understand option -i
[PATCH 03/11] t5302-pack-index: Skip tests of 64-bit offsets if necessary.
[PATCH 04/11] Skip t3902-quoted.sh if the file system does not support
	funny names.

Some changes to the test suite.

[PATCH 05/11] Use is_absolute_path() in sha1_file.c.
[PATCH 06/11] Move #include <sys/select.h> and <sys/ioctl.h> to
	git-compat-util.h.

These two are certainly undisputed.

[PATCH 07/11] builtin run_command: do not exit with -1.

Replaces exit(-1) by exit(255). I don't know if this has any bad consequences on *nix.

[PATCH 08/11] Close files opened by lock_file() before unlinking.

This one was authored by Dscho. It is a definite MUST on Windows.

[PATCH 09/11] Allow a relative builtin template directory.
[PATCH 10/11] Introduce git_etc_gitconfig() that encapsulates access
	of ETC_GITCONFIG.
[PATCH 11/11] Allow ETC_GITCONFIG to be a relative path.

These need probably some discussion. They avoid that $(prefix) is hardcoded and so allows that an arbitrary installation directory.
