Strip namelen out of ce_flags into a ce_namelen field

Browse Source 
Strip the name length from the ce_flags field and move it
into its own ce_namelen field in struct cache_entry. This
will both give us a tiny bit of a performance enhancement
when working with long pathnames and is a refactoring for
more readability of the code.

It enhances readability, by making it more clear what
is a flag, and where the length is stored and make it clear
which functions use stages in comparisions and which only
use the length.

It also makes CE_NAMEMASK private, so that users don't
mistakenly write the name length in the flags.
