ams: bump api version to 1.2.3

dmnt2: fix gdb register output

creport: fix errant )

dmnt2: try to avoid writing out of bounds when generating packets

dmnt2: fix module name detection, add auto-break on hb nro launch

dmnt2: fix missing null-terminator for invalid command error

dmnt2: detect thread name, add monitor get mapping(s), increase buffer sizes

dmnt2: remove memory-map output which does nothing for us

kern/dmnt2: allow retrieval of process info via extension ...

This also fixes ctrl-c break in gdbstub, and fixes crash on unknown monitor cmd.

dmnt2: first pass at wait-for-application

dmnt2: add monitor get base, TODO responses for monitor wait *

dmnt2: add memory-map read, improve module shared-lib names

Adding setting usage to dmnt2 means dmnt2 needs settings access

dmnt: enable experimental standalone usage of gdbstub, while starlink is in dev

ams.mitm: more romfs building space/time tradeoffs. ...

This is needed for Animal Crossing 2.0.0, which has >99000 fucking files.

We now do several passes over dir/file tables instead of one pass,
doing entire hash tables before we touch dir/file tables. Thus we
no longer need to simultaneously allocate hash table and dir/file table space.

In addition, we now do repeated passes building a segment of hash tables
at a time, when insufficient memory is available. Similar is also now the
case for file/dir tables, we try 0x40000 work buffer and divide by 2
until we successfully alloc. We don't allow a work buffer <0x4000, for
write/perf reasons. If a game triggers that, let me know I guess.

Hard to imagine a worse torture-test for this code than animal crossing.

ams: add arm/armv8a to gitignore

ams: update for awareness of architecture revision

creport: print symbols if they're present

ams: bump version to 1.2.2

sprofile: various correctness fixes.

sprofile: fix off-by-one in struct definition, fix GetImportableProfileUrls

kern: fix minor assembly bugs, avoid unnecessary function call in KScheduler hotloop

kern: fix 32-bit light ipc svc handler asm ...

Nintendo used to do what we were doing because the function wasn't directly in the handler table,
but we've always been directly in the handler table, so we were trashing the last four arguments to light ipc
when called from aarch32. Nothing uses this, but needed to be fixed.
