The summary line names the CPU, its thread count, physical memory and,
with param.json, the title ID, name and content version.
APS5_TRACE_BENCH=1 with APS5_TRACE_SUMMARY_EVERY rewrites
aps5-bench-<commit>-<pid>.json.gz at each interval with the time between
every two presents, so reports can be recomputed and checked from raw
frame times. param.json's contentVersion is read when present.

PS4 titles ship sce_sys/param.sfo instead of param.json. When param.json
is absent, the application metadata now reads the title, title ID,
download data size and user defined parameters from param.sfo, and
/data and /download0 are mounted for it as for param.json. param.json
is still preferred when both files exist.
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.
