splicemap: improve error handling when source is hg (
issue2084)
1. Introduced 2 levels of error handling for splicemap files
a. Check the splicemap file for rules which are same across different
types of source repos. This is done through enhancing parsesplicemap
function
b. Check revision string formats. Each repo may have their own format.
This is done usign checkrevformat function
c. Implemented the above two for hg
Test config convert.cvsps.mergefrom config setting.
(Should test similar mergeto feature, but I don't understand it yet.)
Requires builtin cvsps.
$ "$TESTDIR/hghave" cvs || exit 80
$ CVSROOT=`pwd`/cvsrepo
$ export CVSROOT
$ cvscall()
> {
> cvs -f "$@"
> }
output of 'cvs ci' varies unpredictably, so just discard it

create two release branches
$ cvscall -q tag -b v1_0

non-merged change on trunk
$ echo "foo" > file2
$ cvscall -Q add file2

this will create rev 1.3
