Ævar Arnfjörð Bjarmason f69a6e4f07 *.h: move some *_INIT to designated initializers
Move various *_INIT macros to use designated initializers. This helps
readability. I've only picked those leftover macros that were not
touched by another in-flight series of mine which changed others, but
also how initialization was done.

In the case of SUBMODULE_ALTERNATE_SETUP_INIT I've left an explicit
initialization of "error_mode", even though
SUBMODULE_ALTERNATE_ERROR_IGNORE itself is defined as "0". Let's not
peek under the hood and assume that enum fields we know the value of
will stay at "0".

The change to "TESTSUITE_INIT" in "t/helper/test-run-command.c" was
part of an earlier on-list version[1] of c90be786da (test-tool
run-command: fix flip-flop init pattern, 2021-09-11).

Ævar Arnfjörð Bjarmason 608cfd31cf *.h _INIT macros: don't specify fields equal to 0
Change the initialization of "struct strbuf" changed in
cbc0f81d96 (strbuf: use designated initializers in STRBUF_INIT,
2017-07-10) to omit specifying "alloc" and "len", as we do with other
"alloc" and "len" (or "nr") in similar structs.

Let's likewise omit the explicit initialization of all fields in the
"struct ipc_client_connect_option" struct added in
59c7b88198 (simple-ipc: add win32 implementation, 2021-03-15).

Do the same for a few other initializers, e.g. STRVEC_INIT and
CACHE_DEF_INIT.

Finally, start incrementally changing the same pattern in
"t/helper/test-run-command.c". This change was part of an earlier
on-list version[1] of c90be786da (test-tool run-command: fix
flip-flop init pattern, 2021-09-11).

Jeff King 8d133a4653 strvec: use size_t to store nr and alloc
We converted argv_array (which later became strvec) to use size_t in
819f0e76b1 (argv-array: use size_t for count and alloc, 2020-07-28) in
order to avoid the possibility of integer overflow. But later, commit
d70a9eb611 (strvec: rename struct fields, 2020-07-28) accidentally
converted these back to ints!

Those two commits were part of the same patch series. I'm pretty sure
what happened is that they were originally written in the opposite order
and then cleaned up and re-ordered during an interactive rebase. And
when resolving the inevitable conflict, I mistakenly took the "rename"
patch completely, accidentally dropping the type change.

We can correct it now; better late than never.

Jeff King d70a9eb611 strvec: rename struct fields
The "argc" and "argv" names made sense when the struct was argv_array,
but now they're just confusing. Let's rename them to "nr" (which we use
for counts elsewhere) and "v" (which is rather terse, but reads well
when combined with typical variable names like "args.v").

Note that we have to update all of the callers immediately. Playing
tricks with the preprocessor is hard here, because we wouldn't want to
rewrite unrelated tokens.

Jeff King b5eb741a00 strvec: drop argv_array compatibility layer
There are no callers which need it anymore. Any topics in flight will
need to be updated as they get merged in (but the compiler will make
that quite clear).

Jeff King dbbcd44fb4 strvec: rename files from argv-array to strvec
This requires updating #include lines across the code-base, but that's
all fairly mechanical, and was done with:

  git ls-files '*.c' '*.h' |
  xargs perl -i -pe 's/argv-array.h/strvec.h/'
