chg: fallback to original hg if stdio fds are missing

If stdio fds are missing (ex. fd 0 is not present), chg might open
fds that take the numbers 0, and attachio would send the wrong fds
to the client, which might cause unwanted behaviors. Avoid that by
detecting the missing fds and falling back to the original hg.

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    |
