fdfawef324 0ca047e60d fix(libc): size collate<char>::do_transform strings as the console does 
collate<char>::do_transform gave the result std::string a capacity of
exactly its length and threw for results of 4095 characters or more.
The console's libc.prx grows the string from its inline capacity of 15
to length | 15, so a 26-character result has capacity 31 and a 32-byte
allocation. Once capacity + 1 reaches 0x1000 bytes it takes the
over-aligned large allocation that the guest's inlined deallocation
expects: operator new(bytes + 0x27), the data aligned to 32 bytes and
the raw pointer stored just before it. This is the scheme of
Dinkumware's basic_string (_Newsize | _ALLOC_MASK) and of its
_Allocate in <xmemory0> (_BIG_ALLOCATION_THRESHOLD 4096,
_BIG_ALLOCATION_ALIGNMENT 32, _NON_USER_SIZE sizeof(void*) + 31),
including its bad_alloc when bytes + 0x27 would wrap.

do_transform now uses that capacity and allocation; the throw for long
results is gone. The debt entry in docs/dev/debt/libc.md now records
the capacity and large storage as unverified on hardware. guest_collate
checks the capacity and allocation size of a 26-character result, the
last small result (4079 characters, a 4080-byte block) and the first
large one (4080 characters, capacity 4095, a 4096 + 0x27-byte block
with the data aligned to 32 and the raw pointer before it). With main's
LocaleSupport.cpp it aborts at the allocation-size check of the
26-character result (lastSize 27 instead of 32).
