Stop having GET_OID_ONLY_TO_DIE imply GET_OID_QUIETLY in
get_oid_with_context_1().
The *_DIE flag was added in 33bd598c39 (sha1_name.c: teach lookup
context to get_sha1_with_context(), 2012-07-02), and then later
tweaked in 7243ffdd78 (get_sha1: avoid repeating ourselves via
ONLY_TO_DIE, 2016-09-26).
Everything in that commit makes sense, but only for callers that
expect to fail in an initial call to get_oid_with_context_1(), e.g. as
"git show 0017" does via handle_revision_arg(), and then would like to
call get_oid_with_context_1() again via this
maybe_die_on_misspelt_object_name() function.
In the subsequent commit we'll add a new caller that expects to call
this only once, but who would still like to have all the error
messaging that GET_OID_ONLY_TO_DIE gives it, in addition to any
regular errors.

Change the usage output emitted on "git cat-file -h" to group related
options, making it clear to users which options go with which other
ones.
The new output is:
Check object existence or emit object contents
-e check if <object> exists
-p pretty-print <object> content
Emit [broken] object attributes
-t show object type (one of 'blob', 'tree', 'commit', 'tag', ...)
-s show object size
--allow-unknown-type allow -s and -t to work with broken/corrupt objects
Batch objects requested on stdin (or --batch-all-objects)
--batch[=<format>] show full <object> or <rev> contents
--batch-check[=<format>]
like --batch, but don't emit <contents>
--batch-all-objects with --batch[-check]: ignores stdin, batches all known objects
Change or optimize batch output
--buffer buffer --batch output
--follow-symlinks follow in-tree symlinks
--unordered do not order objects before emitting them
Emit object (blob or tree) with conversion or filter (stand-alone, or with batch)
--textconv run textconv on object's content
--filters run filters on object's content
--path blob|tree use a <path> for (--textconv | --filters ); Not with 'batch'
The old usage was:
<type> can be one of: blob, tree, commit, tag
-t show object type
-s show object size
-e exit with zero when there's no error
-p pretty-print object's content
--textconv for blob objects, run textconv on object's content
--filters for blob objects, run filters on object's content
--batch-all-objects show all objects with --batch or --batch-check
--path <blob> use a specific path for --textconv/--filters
--allow-unknown-type allow -s and -t to work with broken/corrupt objects
--buffer buffer --batch output
--batch[=<format>] show info and content of objects fed from the standard input
--batch-check[=<format>]
show info about objects fed from the standard input
--follow-symlinks follow in-tree symlinks (used with --batch or --batch-check)
--unordered do not order --batch-all-objects output
While shorter, I think the new one is easier to understand, as
e.g. "--allow-unknown-type" is grouped with "-t" and "-s", as it can
only be combined with those options. The same goes for "--buffer",
"--unordered" etc.

With the migration of --batch-all-objects to OPT_CMDMODE() in the
preceding commit one bug with combining it and other OPT_CMDMODE()
options was solved, but we were still left with e.g. --buffer silently
being discarded when not in batch mode.
Fix all those bugs, and in addition emit errors telling the user
specifically what options can't be combined with what other options,
before this we'd usually just emit the cryptic usage text and leave
the users to work it out by themselves.
This change is rather large, because to do so we need to untangle the
options processing so that we can not only error out, but emit
sensible errors, and e.g. emit errors about options before errors
about stray argc elements (as they might become valid if the option
were removed).
Some of the output changes ("error:" to "fatal:" with
usage_msg_opt[f]()), but none of the exit codes change, except in
those cases where we silently accepted bad option combinations before,
now we'll error out.

The usage of OPT_CMDMODE() in "cat-file"[1] was added in parallel with
the development of[3] the --batch-all-objects option[4], so we've
since grown[5] checks that it can't be combined with other command
modes, when it should just be made a top-level command-mode
instead. It doesn't combine with --filters, --textconv etc.
By giving parse_options() information about what options are mutually
exclusive with one another we can get the die() message being removed
here for free, we didn't even use that removed message in some cases,
e.g. for both of:
--batch-all-objects --textconv
--batch-all-objects --filters
We'd take the "goto usage" in the "if (opt)" branch, and never reach
the previous message. Now we'll emit e.g.:
$ git cat-file --batch-all-objects --filters
error: option `filters' is incompatible with --batch-all-objects

There's no benefit to defining this at a distance, and it makes the
code harder to read as you've got to scroll up to see the usage that
corresponds to the options.
In subsequent commits I'll make use of usage_msg_opt(), which will be
quite noisy if I have to use the long "cat_file_usage" variable,
there's no other command being defined in this file, so let's rename
it to just "usage".

There were various inaccuracies in the previous SYNOPSIS output,
e.g. "--path" is not something that can optionally go with any options
except --textconv or --filters, as the output implied.
The opening line of the DESCRIPTION section is also "In its first
form[...]", which refers to "git cat-file <type> <object>", but the
SYNOPSIS section wasn't showing that as the first form!
That part of the documentation made sense in
d83a42f34a (Documentation: minor grammatical fixes in
git-cat-file.txt, 2009-03-22) when it was introduced, but since then
various options that were added have made that intro make no sense in
the context it was in. Now the two will match again.
The usage output here is not properly aligned on "master" currently,
but will be with my in-flight 4631cfc20b (parse-options: properly
align continued usage output, 2021-09-21), so let's indent things
correctly in the C code in anticipation of that.

Add a usage_msg_optf() as a shorthand for the sort of
usage_msg_opt(xstrfmt(...)) used in builtin/stash.c. I'll make more
use of this function in builtin/cat-file.c shortly.
The disconnect between the "..." and "fmt" is a bit unusual, but it
works just fine and this keeps it consistent with usage_msg_opt(),
i.e. a caller of it can be moved to usage_msg_optf() and not have to
have its arguments re-arranged.

Add tests for the output that's emitted when we disambiguate
<obj>:<path> in cat-file. This gives us a baseline for improving these
messages.
For e.g. "git blame" we'll emit:
$ git blame HEAD:foo
fatal: no such path 'HEAD:foo' in HEAD
But cat-file doesn't disambiguate these two cases, and just gives the
rather unhelpful:
$ git cat-file --textconv HEAD:foo
fatal: Not a valid object name HEAD:foo

Stress test the usage emitted when options are combined in ways that
isn't supported. Let's test various option combinations, some of these
we buggily allow right now.
E.g. this reveals a bug in 321459439e (cat-file: support
--textconv/--filters in batch mode, 2016-09-09) that we'll fix in a
subsequent commit. We're supposed to be emitting a relevant message
when --batch-all-objects is combined with --textconv or --filters, but
we don't.
The cases of needing to assign to opt=2 in the "opt" loop are because
on those we do the right thing already, in subsequent commits the
"test_expect_failure" cases will be fixed, and the for-loops unified.
