chg: remove manual reload logic

chgserver now validates and reloads configs automatically. Manually reloading
is no longer necessary. Besides, we are deprecating pid files since the server
will periodically check its ownership of the socket file and exit if it does
not own the socket file any longer, which works more reliable than a pid file.
This patch removes the SIGHUP reload logic from both chg server and client.

Test basic functionality of url#rev syntax

  $ hg init repo
  $ cd repo
  $ echo a > a
  $ hg ci -qAm 'add a'
  $ hg branch foo
  marked working directory as branch foo
  (branches are permanent and global, did you want a bookmark?)
  $ echo >> a
  $ hg ci -m 'change a'
  $ cd ..
