Allow Mercurial to build on HP-UX 11
Temporary fix to allow Mercurial to build on HP-UX 11, as the C
compiler on HP-UX 11 doesn't support 'inline' qualifier. The
'__inline' qualifier seemed to be supported, but not without
first resolving other associated issues.
Cleanup after previous changes:
- there are only two states for the exec bit, so no need to override it.
- file_ variable is only once now, so it self.file(f) can be used directly.
Extended test case to test dirstate length bug fixed in
a7e95e3606c7.
Fix 3-way-merge of original parent, workdir and new parent.
The dirstate has to match what is in the repository (what would be
checked out with 'hg update -C'), because the resulting file may be
identical to the new parent, or it may be completely different.
Previously the dirstate wasn't updated, so if you changed the file to
look like the original parent, it might be considered unmodified
relative to the new parent.
dirstate.changes() now distinguishes 'hg remove'd or just deleted files.
Interface is not yet changed.
Non-regular files are considered to be removed or deleted.
Removed the unneeded match(fn) call for adding to the unknown list.
