t0109: chain operations with &&

Without '&&' between operations, we will not detect if strace or cgit
exit with an error status, which would cause a false positive test
status in this case.

Add branch-sort and repo.branch-sort options.

When set to "name", branches are sorted by name, which is the current
default. When set to "age", branches are sorted by the age of the
repository.

This feature was requested by Konstantin Ryabitsev for use on
kernel.org.

tests/: Do not use `sed -i`

"-i" isn't part of the POSIX standard and doesn't work on several
platforms such as OpenBSD. Use a temporary file instead.

t0107: Skip ZIP tests if unzip(1) isn't available

Note that we cannot use skip_all here since some tests have already been
executed when ZIP tests are reached. Use test prerequisites to skip
everything using unzip(1) if the binary is not available instead.

ui-snapshot.c: Prepend "V" when guessing ref names

In cgit_print_snapshot_links() we strip leading "v" and "V", while we
currently only prepend a lower case "v" when parsing a snapshot file
name. This results in broken snapshot links for tags that start with an
upper case "V". Avoid this by prepending a "V" as a fallback.

cgitrc.5.txt: Specify when scan-path must be defined before.

Several options must be specified prior to scan-path. This is consistant
source of user confusion. Document these facts.
