c4d9c79378 treewide: remove unnecessary inclusions of parse-options.h from headers
The headers 'diagnose.h', 'list-objects-filter-options.h',
'ref-filter.h' and 'remote.h' declare option parsing callback
functions with a 'struct option*' parameter, and 'revision.h' declares
an option parsing helper function taking 'struct parse_opt_ctx_t*' and
'struct option*' parameters.  These headers all include
'parse-options.h', although they don't need any of the type
definitions from that header file.  Furthermore,
'list-objects-filter-options.h' and 'ref-filter.h' also define some
OPT_* macros to initialize a 'struct option', but these don't
necessitate the inclusion of parse-options.h in these headers either,
because these macros are only expanded in source files.

Remove these unnecessary inclusions of parse-options.h and use forward
declarations to declare the necessary types.

After this patch none of the header files include parse-options.h
anymore.

With these changes, the build time after modifying only
parse-options.h is reduced by about 30%, and the number of targets
built is almost 20% less:

  Before:

    $ touch parse-options.h && time make -j4 |wc -l
    353

    real    1m1.527s
    user    3m32.205s
    sys	    0m15.903s

  After:

    289

    real    0m39.285s
    user    2m12.540s
    sys     0m11.164s

7ecf193f7d builtin/diagnose.c: add '--mode' option
Create '--mode=<mode>' option in 'git diagnose' to allow users to optionally
select non-default diagnostic information to include in the output archive.
Additionally, document the currently-available modes, emphasizing the
importance of not sharing a '--mode=all' archive publicly due to the
presence of sensitive information.

Note that the option parsing callback - 'option_parse_diagnose()' - is added
to 'diagnose.c' rather than 'builtin/diagnose.c' so that it may be reused in
future callers configuring a diagnostics archive.

33cba726f0 diagnose.c: add option to configure archive contents
Update 'create_diagnostics_archive()' to take an argument 'mode'. When
archiving diagnostics for a repository, 'mode' is used to selectively
include/exclude information based on its value. The initial options for
'mode' are:

* DIAGNOSE_NONE: do not collect any diagnostics or create an archive
  (no-op).
* DIAGNOSE_STATS: collect basic repository metadata (Git version, repo path,
  filesystem available space) as well as sizing and count statistics for the
  repository's objects and packfiles.
* DIAGNOSE_ALL: collect basic repository metadata, sizing/count statistics,
  and copies of the '.git', '.git/hooks', '.git/info', '.git/logs', and
  '.git/objects/info' directories.

These modes are introduced to provide users the option to collect
diagnostics without the sensitive information included in copies of '.git'
dir contents. At the moment, only 'scalar diagnose' uses
'create_diagnostics_archive()' (with a hardcoded 'DIAGNOSE_ALL' mode to
match existing functionality), but more callers will be introduced in
subsequent patches.

Finally, refactor from a hardcoded set of 'add_directory_to_archiver()'
calls to iterative invocations gated by 'DIAGNOSE_ALL'. This allows for
easier future modification of the set of directories to archive and improves
error reporting when 'add_directory_to_archiver()' fails.

bb2c34956a scalar-diagnose: move functionality to common location
Move the core functionality of 'scalar diagnose' into a new 'diagnose.[c,h]'
library to prepare for new callers in the main Git tree generating
diagnostic archives. These callers will be introduced in subsequent patches.

While this patch appears large, it is mostly made up of moving code out of
'scalar.c' and into 'diagnose.c'. Specifically, the functions

- dir_file_stats_objects()
- dir_file_stats()
- count_files()
- loose_objs_stats()
- add_directory_to_archiver()

are all copied verbatim from 'scalar.c'. The 'create_diagnostics_archive()'
function is a mostly identical (partial) copy of 'cmd_diagnose()', with the
primary changes being that 'zip_path' is an input and "Enlistment root" is
corrected to "Repository root" in the archiver log.
