cmdserver: wrap 'pipe' mode server by service object

This is the stub for new mode that will listen for connections on unix domain
socket.

Though --daemon option is not banned in 'pipe' mode, it is useless because
the detached 'pipe' mode server exits immediately due to null stdin. Should
it abort if --daemon is specified with --cmdserver pipe or --stdio?

  $ echo "largefiles =" >> $HGRCPATH

Create the repository outside $HOME since largefiles write to
$HOME/.cache/largefiles.

Whatever ... commit something so we can invoke merge when updating

  $ hg commit -m '3: Merge'

Updating from largefile to normal - no reason to prompt

  $ hg up -r 2
  getting changed largefiles
  0 largefiles updated, 0 removed
  1 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ cat foo
  normal

(the update above used to leave the working dir in a very weird state - clean it
  $ hg up -qr null
  $ hg up -qr 2
)

Updating from normal to largefile - no reason to prompt

  $ hg up -r 3

Systematic testing of merges involving largefiles:

Ancestor: normal  Parent: normal=  Parent: large   result: large
Ancestor: normal  Parent: normal2  Parent: large   result: ?
Ancestor: large   Parent: large=   Parent: normal  result: normal
Ancestor: large   Parent: large2   Parent: normal  result: ?

All cases should try merging both ways.
"=" means same file content.

Prepare test repo:

  $ hg init merges
  $ cd merges
  $ touch f1
  $ hg ci -Aqm "0-root" --config extensions.largefiles=!

Ensure that .hg/largefiles isn't created before largefiles are added
#if unix-permissions
  $ chmod 555 .hg
#endif
  $ hg status
#if unix-permissions
  $ chmod 755 .hg
#endif
