fix a bug in findwixt() which caused pack files with missing parent commits
The 'nskip' variable is supposed to reflect commits which are waiting on
the queue and have the 'skip' color. Only increment 'nskip' when adding
such commits to the queue.
Problem observed with got send -T and a tag pointing to a deleted branch.
Test to reproduce the bug written by op@.

shrink struct got_pack_meta a bit by removing the have_reused_delta flag
This flag can be expressed as m->reused_delta_offset != 0 because all
deltas in valid pack files will be written at a non-zero offset.
We allocate a huge number of these structs during packing, so every
little bit helps.

reduce the amount of memory used for caching deltas during deltification
With files sorted properly for deltification we produce better deltas
but end up consuming more memory and risk running into OpenBSD ulimits
during packing. To compensate, reduce the threshold for the amount of
delta data we store in memory, spooling more deltas into the cache file.

store a path hash instead of a verbatim path in pack meta data
This reduces memory use by gotadmin pack. The goal is to sort files
which share a path next to each other for deltification. A hash of
the path is good enough for this purpose and consumes less memory
than a verbatim copy of the path. Git does something similar.

fix paths stored in pack meta data, improving file deltification
The old code was broken and stored an empty path or filenames, instead
of a repository-relative path. Which means we didn't sort files for
deltification as was intended.
Fixing this provides much better deltas in large pack files written by
gotadmin pack -a. In my test case, pack size changed from 2GB to 1.5GB.

revert "Skip poll(2) if an imsgbuf has a non-empty read buffer"
imsg_read() will call recvmsg() on the file descriptor regardless
of the read buffer's state, so we should ensure that data is ready.
The read buffer is used by imsg_get(), not imsg_read().
We already call imsg_get() before imsg_read(), and call the latter
only if imsg_get() returns zero.

run the search for deltas to reuse in got-read-pack
This significantly speeds up the deltification step of packing by
avoiding imsg traffic. gotadmin no longer requests individual raw
deltas from got-read-pack to check whether it can reuse them.
Instead, got-read-pack obtains a list of objects we want to pack,
and hands back the list of all deltas in its pack file which can be
reused. Messages are now batched such that imsg buffers are filled
as much as possible.
Another advantage is that deltas we are not going to reuse will
no longer be written to the delta cache file, saving disk space.
Before this patch, any raw delta candidate was written to the
delta cache file by got-read-pack, and the decision whether to
reuse the delta happened afterwards in the gotadmin process.
Code for reading individual raw deltas is now unused and could be
removed at some point.

speed up initial stage of packing by adding a "skip" commit color
The skip color marks boundary commits and their ancestors. Boundary commits
are reachable both via references which we want to exclude from the pack,
and via references which we want to include in the pack.
We continue processing commit history up to the point we are left with only
skip commits on the queue. This can speed up findtwixt() significantly and
avoids wrong results produced by the old algorithm which made no distinction
between "drop" and "skip".
This idea was first implemented by Michael Forney for git9:
https://git.9front.org/plan9front/plan9front/2e47badb88312c5c045a8042dc2ef80148e5ab47/commit.html
Michael's log message for git9 is reproduced below:
git/query: refactor graph painting algorithm (findtwixt, lca)
We now keep track of 3 sets during traversal:
- keep: commits we've reached from head commits
- drop: commits we've reached from tail commits
- skip: ancestors of commits in both 'keep' and 'drop'
Commits in 'keep' and/or 'drop' may be added later to the 'skip' set
if we discover later that they are part of a common subgraph of the
head and tail commits.
From these sets we can calculate the commits we are interested in:
lca commits are those in 'keep' and 'drop', but not in 'skip'.
findtwixt commits are those in 'keep', but not in 'drop' or 'skip'.
The "LCA" commit returned is a common ancestor such that there are no
other common ancestors that can reach that commit. Although there can
be multiple commits that meet this criteria, where one is technically
lower on the commit-graph than the other, these cases only happen in
complex merge arrangements and any choice is likely a decent merge
base.
Repainting is now done in paint() directly. When we find a boundary
commit, we switch our paint color to 'skip'. 'skip' painting does
not stop when it hits another color; we continue until we are left
with only 'skip' commits on the queue.
This fixes several mishandled cases in the current algorithm:
1. If we hit the common subgraph from tail commits first (if the tail
commit was newer than the head commit), we ended up traversing the
entire commit graph. This is because we couldn't distinguish
between 'drop' commits that were part of the common subgraph, and
those that were still looking for it.
2. If we traversed through an initial part of the common subgraph from
head commits before reaching it from tail commits, these commits
were returned from findtwixt even though they were also reachable
from tail commits.
3. In the same case as 2, we might end up choosing an incorrect
commit as the LCA, which is an ancestor of the real LCA.

got patch: prefer new name if not /dev/null and not a git-style diff
This fixes a common issue when for e.g. generating patches with
$ diff -u foo.orig foo
where 'got patch' failed because 'foo.orig' has an 'unexpected status'.

move got_patch file status checking in worktree.c
check_file_status used got_worktree_status to check if the file was in
an allowed state, but it's wrong since the callback is not invoked on
unchanged files.
While here also fix a relate bug: unlink(newpath) is in the wrong spot
and ends up removing files even when it shouldn't, so move it early in
the got_worktree_schedule_* error handling.
Finally, update the appropriate test case. It was passing before
because got_worktree_schedule_add returned GOT_ERR_FILE_STATUS, not
because check_file_status failed.
