On Linux every module resolves its references through one global scope,
and the guest modules are listed ahead of the host prx. When a title
bundles its own libc.prx, the host libc and the other host prx bound
their references to their own NIDs to the guest libc, so the host libc
built its standard streams on top of the guest _Stdout.
The exports of guest modules, and the guest and executable imports that
a guest module satisfies, now carry a #guest suffix. The title's imports
still reach the guest modules first, and a host prx only sees host
definitions, as on Windows. sceKernelDlsym also looks for the suffixed
name.
Returns 1 when the address lies in an executable PT_LOAD segment of the
given dl_phdr_info, following FreeBSD lib/libc/gen/elf_utils.c (9.x and
11.x branches). The stub parameters become (dl_phdr_info*, void*) to
match the FreeBSD declaration; a null dl_phdr_info throws.

Renames template parameters to the TKey-style the conventions doc
requires (TValue, TFunction), removes the extern "C" close comment
(not one of the two allowed structural exceptions), and replaces
the magic error/flag numbers left after the previous comment
cleanup with the existing SCE_KERNEL_ERROR_* constants and a named
RTLD_NOW constant so the code documents itself.
Comments in this codebase may only mark technical debt (per
docs/dev/CONVENTIONS.md), plus the #endif and namespace-close
structural exceptions. Removes the descriptive comments added on
this branch across PreciseWait.hpp, FormattingWide.cpp, the
direct-memory pool query/free-run plumbing, and the module loader
wiring, keeping the two allowed structural markers intact.
- DirectMemory: track each allocated block's type and extent in the
physical pool (DirectMemoryBlock), splitting the record on a partial
free, and expose DirectMemoryQueryBlock/DirectMemoryFreeRun. Wires
sceKernelDirectMemoryQuery to answer with the real allocated range
and type instead of a hardcoded one-page/type-3 guess, and
sceKernelAvailableDirectMemorySize to report the actual free run
instead of the whole remaining aperture. DirectMemory.cpp's mapping
path already tolerates MAP_FIXED overlap into a registered range and
already has honor-then-fallback address-hint handling and an
ignored-flags mask, so it is unchanged here.
- MemoryPoolExport: implement sceKernelMemoryPoolBatch/Commit/Decommit/
Expand/GetBlockStats/Reserve (previously all dead stubs) using the
existing DoMprotect/DirectMemoryAlloc/DoReserveVirtual primitives and
a small pool-state block counter.
- Module: wire sceKernelDlsym/sceKernelLoadStartModule/
sceKernelStopUnloadModule to the existing host-module loader
(dlopen_nid_postfix/dlsym_nid_postfix/dlclose_nid_postfix), replacing
dead stubs. sceKernelGetModuleInfoForUnwind/FromAddr are unrelated
and left as-is.
