max_tree_depth: lower it for MSVC to avoid stack overflows
There seems to be some internal stack overflow detection in MSVC's
`malloc()` machinery that seems to be independent of the `stack reserve`
and `heap reserve` sizes specified in the executable (editable via
`EDITBIN /STACK:<n> <exe>` and `EDITBIN /HEAP:<n> <exe>`).
In the newly test cases added by `jk/tree-name-and-depth-limit`, this
stack overflow detection is unfortunately triggered before Git can print
out the error message about too-deep trees and exit gracefully. Instead,
it exits with `STATUS_STACK_OVERFLOW`. This corresponds to the numeric
value -1073741571, something the MSYS2 runtime we sadly need to use to
run Git's test suite cannot handle and which it internally maps to the
exit code 127. Git's test suite, in turn, mistakes this to mean that the
command was not found, and fails both test cases.
Here is an example stack trace from an example run:
I verified manually that `traverse_trees_cur_depth` was 562 when that
happened, which is far below the 2048 that were already accepted into
Git as a hard limit.
Despite many attempts to figure out which of the internals trigger this
`STATUS_STACK_OVERFLOW` and how to maybe increase certain sizes to avoid
running into this issue and let Git behave the same way as under Linux,
I failed to find any build-time/runtime knob we could turn to that
effect.
Note: even switching to using a different allocator (I used mimalloc
because that's what Git for Windows uses for its GCC builds) does not
help, as the zlib code used to unpack compressed pack entries _still_
uses the regular `malloc()`. And runs into the same issue.
Note also: switching to using a different allocator _also_ for zlib code
seems _also_ not to help. I tried that, and it still exited with
`STATUS_STACK_OVERFLOW` that seems to have been triggered by a
`mi_assert_internal()`, i.e. an internal assertion of mimalloc...
So the best bet to work around this for now seems to just lower the
maximum allowed tree depth _even further_ for MSVC builds.

am: simplify --show-current-patch handling
Let the parse-options code detect and handle the use of options that are
incompatible with --show-current-patch. This requires exposing the
distinction between the "raw" and "diff" sub-modes. Do that by
splitting the mode RESUME_SHOW_PATCH into RESUME_SHOW_PATCH_RAW and
RESUME_SHOW_PATCH_DIFF and stop tracking sub-modes in a separate struct.
The result is a simpler callback function and more precise error
messages. The original reports a spurious argument or a NULL pointer:
$ git am --show-current-patch --show-current-patch=diff

$ git am --show-current-patch=diff --show-current-patch

parse-options: make CMDMODE errors more precise
Only a single PARSE_OPT_CMDMODE option can be specified for the same
variable at the same time. This is enforced by get_value(), but the
error messages are imprecise in three ways:
1. If a non-PARSE_OPT_CMDMODE option changes the value variable of a
PARSE_OPT_CMDMODE option then an ominously vague message is shown:
Fortunately this can currently only happen in the test helper; actual
Git commands don't share the same variable for the value of options with
and without the flag PARSE_OPT_CMDMODE.
2. If there are multiple options with the same value (synonyms), then
the one that is defined first is shown rather than the one actually
given on the command line, which is confusing:
$ git am --resolved --quit
error: option `quit' is incompatible with --continue
3. Arguments of PARSE_OPT_CMDMODE options are not handled by the
parse-option machinery. This is left to the callback function. We
currently only have a single affected option, --show-current-patch of
git am. Errors for it can show an argument that was not actually given
on the command line:
$ git am --show-current-patch --show-current-patch=diff
error: options '--show-current-patch=diff' and '--show-current-patch=raw' cannot be used together
The options --show-current-patch and --show-current-patch=raw are
synonyms, but the error accuses the user of input they did not actually
made. Or it can awkwardly print a NULL pointer:
$ git am --show-current-patch=diff --show-current-patch
error: options '--show-current-patch=(null)' and '--show-current-patch=diff' cannot be used together
The reasons for these shortcomings is that the current code checks
incompatibility only when encountering a PARSE_OPT_CMDMODE option at the
command line, and that it searches the previous incompatible option by
value.
Fix the first two points by checking all PARSE_OPT_CMDMODE variables
after parsing each option and by storing all relevant details if their
value changed. Do that whether or not the changing options has the flag
PARSE_OPT_CMDMODE set. Report an incompatibility only if two options
change the variable to different values and at least one of them is a
PARSE_OPT_CMDMODE option. This changes the output of the first three
examples above to:
$ t/helper/test-tool parse-options --set23 --mode1
error: --mode1 is incompatible with --set23
$ t/helper/test-tool parse-options --mode1 --set23
error: --set23 is incompatible with --mode1
$ git am --resolved --quit
error: --quit is incompatible with --resolved
Store the argument of PARSE_OPT_CMDMODE options of type OPTION_CALLBACK
as well to allow taking over the responsibility for compatibility
checking from the callback function. The next patch will use this
capability to fix the messages for git am --show-current-patch.
Use a linked list for storing the PARSE_OPT_CMDMODE variables. This
somewhat outdated data structure is simple and suffices, as the number
of elements per command is currently only zero or one. We do support
multiple different command modes variables per command, but I don't
expect that we'd ever use a significant number of them. Once we do we
can switch to a hashmap.
Since we no longer need to search the conflicting option, the all_opts
parameter of get_value() is no longer used. Remove it.
Extend the tests to check for both conflicting option names, but don't
insist on a particular order.
