ncurses installs <term.h> and defines struct term. In a file that
includes both headers, an ncurses TERMINAL * and this library's terminal
are silently the same type. The name wsap_vtcore avoids the clash.
The public header is now <wsap_vtcore/wsap_vtcore.h>. Every global
symbol uses the wsap_vtcore_ prefix, every macro uses WSAP_VTCORE_, and
the shared library is libwsap_vtcore.so.0. The default terminal name is
now "wsap_vtcore". The ISA override variable is WSAP_VTCORE_ISA.
No other behavior changes. The amalgamation writes wsap_vtcore.c and
wsap_vtcore.h.

term_write_begin spun on an atomic sequence word. A waiter burned CPU,
and with no priority inheritance a SCHED_FIFO waiter could starve a
preempted holder on the same CPU. The writer section is now a pthread
mutex with PTHREAD_PRIO_INHERIT where the platform has it, and an SRWLOCK
on Windows. Re-entry on the owning thread still only counts the depth.
The platform wrapper (init, lock, unlock, destroy) is in compat.h. term_new
initializes the mutex, and term_free destroys it. Meson links the thread
library into the core, term_dep, and term_internal_dep. The README,
term.h, and the amalgamation note say that POSIX needs -pthread.
Tests: the feed and snapshot thread test now checks the final screen and
history against a serial reference. A new test checks that term_lock
nests and that another thread waits for the last term_unlock.

The pkg-config file put include/term on the host's include path, so
ncurses' term.h could be picked up in place of ours. Hosts now write
<term/term.h> and the package adds only its include directory.
The installed Unicode API had unprefixed names that collide with host
symbols and macros. Rename them: term_ for functions, types, and static
tables, TERM_ for macros and include guards. unicode_data.inc and
tools/generate_unicode.py are renamed to match. The generator's inputs
here are Unicode 15.1 and the checked-in table is 18.0.0, so the table
data was not regenerated. Only the declarations were checked against
the generator.
utf8.h casts the malloc result so it compiles as C++.
header_test.sh now includes <term/term.h> with only include/ on the path.
It also checks that a host which defines unicode_width, UTF8_ACCEPT,
GRAPHEME_MAX_LEN, in_ranges, and similar names compiles with the Unicode
headers as C11 and C++, in both declaration orders.

The core now builds, tests, and benchmarks alone, as a Meson subproject
with no dependency on the main tree.
- include/term/ holds term.h and the header-only unicode/. src/ holds
the core and its private headers. The main tree gets only
include/term through term_dep, so it cannot reach a private header.
- The term tests, the term benchmarks, the Kitty parser suite, and
tools/amalgamate.py and tools/generate_unicode.py move with it. The
tests run as term:<name>.
- The main build passes its -march (arch_flag) and b_ndebug to the
subproject. A directory configured before this commit needs
meson configure -Dterm:arch_flag=-march=... once.
- The term tests compile with -UNDEBUG. They do work inside assert.
- The subproject exports term_test_dep with term_api.h, for the main
tree's render, thumbnail, color, and selection tests.
- The Kitty bridge used struct vector2i and has not compiled since the
public API redesign. It builds again. 2 of its 14 tests fail: REP
after a tab, and a cursor report after a resize.
- dirgraph.py drops the term and unicode layers. Its self-test uses pty.
- The symbols test ignores the __odr_asan symbols that ASan adds.
