initfs/tools: buffer inode table writes in memory and flush with a
single write_all_at instead of one syscall per inode header.
randd: build a proper entropy pool using SHA-256 that mixes hardware RNG
(RDRAND/RNDRRS) with timing-derived entropy. The pool is re-seeded
every 4096 reads and on every write. User-supplied entropy from writes
is added to the pool rather than directly replacing the PRNG state.
ptyd: VLNEXT now properly quotes the next input byte — sets a flag that
causes the next byte to bypass all control-character processing and be
pushed directly to the line buffer. VDISCARD now flushes the cooked
input buffer instead of being a silent no-op.
