The libarchive source tree is littered with `__FBSDID("$FreeBSD.*")` and
'$FreeBSD$' tags left over from extracting it from FreeBSD's Subversion
repo. They never made sense for a git repo as git doesn't expand them
and FreeBSD has now removed `$FreeBSD$` from most local source files so
these stand out.
In addition to `__FBSDID` I've removed `__RCSID` which was used once for
a `$NetBSD$` expansion. There might be more of a case to be made for
preserving this one as a diff-reduction measure, but it seems mostly
pointless.
This builds and tests pass except for
libarchive_test_read_disk_directory_traversals which failed on master as
well.
normalize it to avoid the scene that two filenames in one directory are, of course,
different byte sequence but they have the same sight because of NFD and NFC.
Second reason is that iconv cannot correctly convert NFD characters to other
character-set so we have to convert NFD to NFC before iconv handle it unless
iconv supports UTF-8-MAC. Third reason is for matching filenames, if filenames
in archives are NFD and the platform is not MAC OS, the uses cannot specify
the filename the uses want to extract although the users can see the filename
by listing. Recently NFD can be displayed on some platforms but creating NFD
requires character-set conversion utility, in particular that input of NFD
string is hard on Windows platform.
