subrepo: replace "_calcfilehash" invocation by "vfs.tryread"

"_calcfilehash" can be completely replaced by simple "vfs.tryread"
invocation.

    def _calcfilehash(filename):
        data = ''
        if os.path.exists(filename):
            fd = open(filename, 'rb')
            data = fd.read()
            fd.close()
        return util.sha1(data).hexdigest()

Building absolute path "absname" up by "self._repo.join" for files in
"filelist" is avoided, because "vfs.tryread" does so internally.

import sys

globalvars = {}
lines = sys.stdin.readlines()
while lines:
    l = lines.pop(0)
    if l.startswith('SALT'):
        print l[:-1]
    elif l.startswith('>>> '):
        snippet = l[4:]
        while lines and lines[0].startswith('... '):
            l = lines.pop(0)
            snippet += l[4:]
        c = compile(snippet, '<heredoc>', 'single')
        try:
            exec c in globalvars
        except Exception, inst:
            print repr(inst)
