When rolling back the lockfile, call close_lock_file() so that the
lock_file's fd field gets set back to -1. This keeps the lock_file
object in a valid state, which is important because these objects are
allowed to be reused. It also makes it unnecessary to check whether
the file has already been closed, because close_lock_file() takes care
of that.

mishandle "one side deleted, the other side did not touch it" in a
rare corner case, where the other side actually did touch to cause

The following issue was found by scan.coverity.com (ID: 1049510),
and claimed to be likely a copy-paste mistake.
Introduced in 331a1838b (2010-07-02, Try normalizing files
to avoid delete/modify conflicts when merging), which is
quite a long time ago, so I'm rather unsure if it's of any impact
or just went unnoticed.
The line after the changed line has a comparison of 'o.len' to 'a.len',
so we should assume the lengths may be different.
I'd be happy to have a test for this bug(?) attached to
t6031-merge-recursive.sh, but I did not manage to
come up with a test in a reasonable amount of time.

Windows does not have POSIX-like signals, and so we ignore all
operations on the non-existent signal mask machinery.
Do not turn sigemptyset into a function, but leave it a macro that
erases the code in the argument because it is used to set sa_mask
of a struct sigaction, but our dummy in mingw.h does not have that
member.
