Add trace2 region and data events describing attempts to deserialize
status data using a status cache.
A category:status, label:deserialize region is pushed around the
deserialize code.
Deserialization results when reading from a file are:
category:status, path = <path>
category:status, polled = <number_of_attempts>
category:status, result = "ok" | "reject"
When reading from STDIN are:
category:status, path = "STDIN"
category:status, result = "ok" | "reject"
Status will fallback and run a normal status scan when a "reject"
is reported (unless "--deserialize-wait=fail").
If "ok" is reported, status was able to use the status cache and
avoid scanning the workdir.
Additionally, a cmd_mode is emitted for each step: collection,
deserialization, and serialization. For example, if deserialization
is attempted and fails and status falls back to actually computing
the status, a cmd_mode message containing "deserialize" is issued
and then a cmd_mode for "collect" is issued.
Also, if deserialization fails, a data message containing the
rejection reason is emitted.

Fix crash in `git status -v` by setting `des_s->repo`
to a non-null value.
Upstream changes to eliminate use of `the_repository`
added a `repo` field to `struct status`. And calls in
`wt-status.c` to `repo_init_revisions()` were changed
to pass `s->repo` rather than `the_repository`.
The status deserialization code was not updated to
actually set `s->repo` before common code passed the
value to OID routines.
This caused a segfault when verbose output was requested.

With the "--untracked-files=complete" option status computes a
superset of the untracked files. We use this when writing the
status cache. If subsequent deserialize commands ask for either
the complete set or one of the "no", "normal", or "all" subsets,
it can still use the cache file because of filtering in the
deserialize parser.
When running status with the "-uno" option, the long format
status would print a "(use -u to show untracked files)" hint.
When deserializing with the "-uno" option and using a cache computed
with "-ucomplete", the "nothing to commit, working tree clean" message
would be printed instead of the hint.
It was easy to miss because the correct hint message was printed
if the cache was rejected for any reason (and status did the full
fallback).
The "struct wt_status des" structure was initialized with the
content of the status cache (and thus defaulted to "complete").
This change sets "des.show_untracked_files" to the requested
subset from the command-line or config. This allows the long
format to print the hint.

Teach `git status --deserialize` to either wait indefintely
or immediately fail if the status serialization cache file
is stale.

Changes to the global or repo-local excludes files can change the
results returned by "git status" for untracked files. Therefore,
it is important that the exclude-file values used during serialization
are still current at the time of deserialization.
Teach "git status --serialize" to report metadata on the user's global
exclude file (which defaults to "$XDG_HOME/git/ignore") and for the
repo-local excludes file (which is in ".git/info/excludes"). Serialize
will record the pathnames and mtimes for these files in the serialization
header (next to the mtime data for the .git/index file).
Teach "git status --deserialize" to validate this new metadata. If either
exclude file has changed since the serialization-cache-file was written,
then deserialize will reject the cache file and force a full/normal status
run.

Fix "git status --deserialize" to correctly report both pathnames
for renames. Add a test case to verify.
A change was made upstream that added an additional "rename_status"
field to the "struct wt_status_change_data" structure. It is used
during the various print routines to decide if 2 pathnames need to
be printed.

wt-status.c: rename rename-related fields in wt_status_change_data
The fix here is to add that field to the status cache data.

Teach status deserialize code to reject status cache
when printing in porcelain V2 and there are unresolved
conflicts in the cache file. A follow-on task might
extend the cache format to include this additiona data.

Teach STATUS to optionally serialize the results of a
status computation to a file.
Teach STATUS to optionally read an existing serialization
file and simply print the results, rather than actually
scanning.
This is intended for immediate status results on extremely
large repos and assumes the use of a service/daemon to
maintain a fresh current status snapshot.
2021-10-30: packet_read() changed its prototype in ec9a37d (pkt-line.[ch]:
remove unused packet_read_line_buf(), 2021-10-14).
2021-10-30: sscanf() now does an extra check that "%d" goes into an "int"
and complains about "uint32_t". Replacing with "%u" fixes the compile-time
error.
2021-10-30: string_list_init() was removed by abf897b (string-list.[ch]:
remove string_list_init() compatibility function, 2021-09-28), so we need to
initialize manually.
