templatefuncs: add truncate parameter to pad

Details

Summary

Add a truncate option to pad that additionally truncates the text to the pad
width if it is wider.

Since color codes can cause a problem with this, when the text is truncated,
the color codes are also stripped. Users of the truncate option should label
the text outside the pad.

This is necessary to recreate something like the original output for hg absorb using the template language. It also allows inclusion of the commit message in the rows of the absorb output, using a template spec like:

hg absorb -pn -T '{ifeq(linetype,"summary","\n{count} changesets affected",ifeq(linetype,"path","showing changes for {label("absorb.path",path)}","{label("absorb.node", pad(node, 7, truncate=true))} {label("yellow", pad(desc, 30, truncate=true))} {label("diff.{linetype}", "{diffchar}{inserted}{deleted}{hunk}")}"))}\n'
