workingctx: eliminate remove function

Inlining it into it's last remaining call place in cmdutil.copy.

Note that cmdutil.copy is called with the wlock already held, so no additional
locking is needed to call util.unlinkpath.

We do not need to wrap the util.unlinkpath call into a try block, because
at that point we already know whether abssrc exists or not -- thanks to the
preceding util.copyfile call. Adding a new local 'srcexists' in cmdutil.copy
for that purpose.

# Pass all working directory files through check-code.py

import sys, os, imp
rootdir = os.path.abspath(os.path.join(os.path.dirname(sys.argv[0]), '..'))
if not os.path.isdir(os.path.join(rootdir, '.hg')):
    sys.stderr.write('skipped: cannot check code on non-repository sources\n')
    sys.exit(80)

checkpath = os.path.join(rootdir, 'contrib/check-code.py')
checkcode = imp.load_source('checkcode', checkpath)

from mercurial import hg, ui
u = ui.ui()
repo = hg.repository(u, rootdir)
checked = 0
wctx = repo[None]
for f in wctx:
    # ignore removed and unknown files
    if f not in wctx:
        continue
    checked += 1
    checkcode.checkfile(os.path.join(rootdir, f))
if not checked:
    sys.stderr.write('no file checked!\n')
