Read the optional aligned budget from param.json and apply it consistently to configured, available and mapped flexible memory. Add parser and allocation regression coverage.
sceAppContentAppParamGetInt numbers the SKU flag 0 and
USER_DEFINED_PARAM_1..4 as 1..4 (fpPS4 ps4_libsceappcontent). Id 1
returned the SKU flag and 2..5 returned zero. UFC 6 (PPSA23566) checks
that param 1 is its title number, userDefinedParam1 in param.json, and
crashes otherwise. Absent params read as zero.

Only the lines this branch added lose their comments; the commits before
keep them, with the reasoning behind each change, for whoever digs into
that code later.

libkernel:
- direct memory keeps its contents per physical page across unmap and
remap; a page mapped at two live addresses at once throws
- sceKernelDirectMemoryQuery answers from tracked allocations
- SCE protections read back as set, GPU and AMPR bits included
- APR prefix path resolve, file size and stat by id, positional reads,
fsync/pread/pwrite; directories open as descriptors on Windows
- sceKernelCheckReachability, getpeername, shutdown
- Dinkumware C11 threads (_Mtx_*, _Cnd_*, _Thrd_*) in the title libc
layout; any pthread stack size, rounded at thread creation
libc:
- unaddressed guest mappings go to the system-managed area from
0x2_0000_0000, leaving the application area to fixed mappings
- the process starts in /app0
- guest sscanf on Windows; a null %s prints as (null) as on FreeBSD
- localeconv, _FNan, _FDtest, _FExp, __udivti3, wcsncpy_s, aligned
operator new, _Throw_Cpp_error
Tests: direct memory following physical pages, guest formatting.
