naming: shm → shared_memory — 'shm' is a Unix clipping, not an acronym

Browse Source 
Per docs/coding-standards.md (no Unix-abbreviation exception): syscalls
shared_memory_create/map/physical, kernel SharedMemoryObject + handlers,
runtime.shared_memory (library/runtime/shared-memory.zig), the
shared-memory-server/-client test services, the shared-memory QEMU case,
and docs incl. vdso.md's danos_shared_memory_*. 87/87 QEMU tests pass.

@@ -119,7 +119,7 @@ One table entry per kernel call, C ABI (System V AMD64), names prefixed
returns are `u64`, errors return as negative values exactly as today.
The calls that return two values in `rax:rdx` today — `dma_alloc`
(virtual_address + physical_address), `msi_bind` (address + data), `shm_create` (virtual_address + handle) —
(virtual_address + physical_address), `msi_bind` (address + data), `shared_memory_create` (virtual_address + handle) —
become functions returning a two-`u64` struct. The System V ABI returns a
16-byte struct in `rax:rdx`, so the stub is a plain `syscall; ret` — the
C-ABI spelling of the existing convention, at zero cost.
