convert: Make P4 conversion cope with keywords, binary files and symbolic links.
Convert now handles errors from p4 during conversion more gracefully.
If keyword expansion is enabled in a P4 file then keywords will be
unexpanded in hg.
Added testcase for p4 filetypes and keyword (un)expansion.
This testcase ignores UTF and Apple files to avoid binary data.
Edited by pmezard: fixed collation issue on OSX
