Implement the EGL 1.4 and OpenGL ES 2.0 exports that do not need a shader compiler or rasterizer as a host-side state machine following the Khronos specifications: the default display, a single RGBA8/depth16/stencil8 pbuffer configuration, ES2 contexts with share groups, per-thread current state and errors, buffers, textures with mipmap generation, renderbuffers, framebuffers and their completeness, shader and program objects, vertex attributes, every fixed-function state setter and query, clears, pixel uploads, copies and reads on CPU storage.
The 22 unknown NIDs are named from the NID database and the Piglet, Orbis texture and compositor exports, together with shader compilation, program linking and reflection, uniforms, draws, native window surfaces and the Sony-specific APIs, stay NotImplemented_nid_no_patch; the gaps are in docs/dev/debt/libSceGLSlimVSH.md.
Preserve the nearbyint implementation and regression coverage while incorporating current main. The write-watch registration prerequisite is now part of main.
Validation: freshly compiled production MathExact.cpp regression passes; ASan/UBSan passes with detect_leaks=0. The same fixture compiles against main Math.cpp and fails at the FE_INEXACT assertion (exit 134). Conventions, whitespace and 235 script registrations pass. Full product build and full CTest were not rerun for this synchronization.
A title is jailed (agreed on #11216). FreeBSD 11.4 prison_priv_check denies
PRIV_SCHED_RTPRIO, PRIV_SCHED_SET and PRIV_SCHED_SETPRIORITY to a jailed caller.

FreeBSD 11.4 ufs_setattr refuses a change of any SF_* flag to a caller without PRIV_VFS_SYSFLAGS, which prison_priv_check denies a jailed root without allow.chflags. Under the credential model agreed on #11216 every SF_* flag now fails with EPERM, after the EOPNOTSUPP check for unknown bits, instead of throwing.

The trap was released when FlushPending took the image out of the pending
registry, before it waited for GpuMutex, so a read in between saw the old
bytes; cache eviction and explicit write-backs did not release it at all.
Every store now releases it in writeBackLayers: after recording the GPU copy
into the import, or before the first CPU access on the CPU path, which also
releases the traps of other images on the same pages. A trapped image is
stored whole, and direct memory mapped at a second address is not trapped.

Before a label, a pending linear or small storage image that shares no page
with another pending or storing image now gets a write-watch read trap
instead of its store. The first access to its pages stores it through the
host-read hook; any other store releases the trap first.
APS5_NO_LABEL_READ_TRAP=1 keeps the store at the label.

GuestWriteWatchTrapReads takes all access to the pages of a range until
the resolver set with GuestWriteWatchSetReadTrapResolver has run for it.
A fault on a trapped page waits while the resolver runs on the watch's
own thread; host writes and GuestWriteWatchProtect run it first on the
calling thread. Collections keep trapped pages inaccessible, and
registering or unregistering memory drops its traps.
