rust-utils: move the `filesystem_now` function to a util
This is going to be useful for an upcoming `hg update` fastpath.

convert fresh repo and also check localtimezone option
NOTE: This doesn't check all time zones -- it merely determines that
the configuration option is taking effect.
An arbitrary (U.S.) time zone is used here. TZ=US/Hawaii is selected
since it does not use DST (unlike other U.S. time zones) and is always
a fixed difference from UTC.
This choice is limited to work on Linux environments. At least on
FreeBSD 11 this timezone is not known. A better choice is
TZ=Pacific/Johnston. On Linux "US/Hawaii" is just a symlink to this
name and also it is known on FreeBSD and on Solaris.

Test transcoding CVS log messages (issue5597)
=============================================
To emulate commit messages in (non-ascii) multiple encodings portably,
this test scenario writes CVS history file (*,v file) directly via
python code.
Commit messages of version 1.2 - 1.4 use u3042 in 3 encodings below.
|encoding |byte sequence | decodable as: |
| | | utf-8 euc-jp cp932 |
+----------+--------------+--------------------+
|utf-8 |\xe3\x81\x82 | o x x |
|euc-jp |\xa4\xa2 | x o o |
|cp932 |\x82\xa0 | x x o |
