build: chg build was failing when the base directory contained spaces

build: initial version detection by make deb/rpm was missing quoting

build: make install in "/doc" failed if the destination dir contained spaces This and the following commits try to add the necessary quoting in the build scripts to make the process more robust. The target for now is rendering "make deb" successful even when the base directory contains spaces (eg. "/opt/mercu rial"). The build process should succeed without scattering files in spurious directories (eg.: "/opt/mercu/usr/bin/hg").

strip: take branch into account when selecting update target (issue5540) Test contributed by Matt Harbison Keep the same behavior in most cases (i.e. first parent of the first root of stripped changsets), but if the branch differs from wdir's, try to find another parent of stripped commits that is on the same branch.

scmutil: factor out building of transaction summary callback In registersummarycallback(), we extra generic bits of the existing "reportsummary" function into a decorator which will be used in forthcoming changesets to add new summary callbacks.

scmutil: factor out transaction name lookup in registersummarycallback() Add an inner txmatch function in registersummarycallback() factoring out the logic to determine if the transaction matches a particular sources set. We'll reuse this function to add some new report logic in the new changeset.
