Sync the relibc fork with 50 upstream commits (socket layer rework,
exec/signal/ptrace/path/timer updates, pthread cleanup, ld_so lifecycle
work bringing mark_ready/run_fini into the tree, dynamically-linked
init support, start.rs allocator-model rewrite, test harness updates).
Satisfies the verify-fork-functions gate (2 previously-missing ld_so
functions now present).
Conflicts resolved (4 files; 46 auto-merged):
- src/start.rs: took upstream's version wholesale. Upstream moved
allocator/linker initialization into ld_so's new lifecycle (the
mark_ready/run_fini work this merge brings in), superseding the RB
alloc_init cluster; the old model's function was already merged out
and its lone call would not compile.
- redox-rt/src/sys.rs: kept the RB refresh flow with the non-fatal
lseek fallback (upstream adopted the refresh as a fatal '?' —
RB's conservative fallback protects spawn for uid-dropped /
namespace-restricted exec where the kernel cannot refresh).
- src/platform/redox/exec.rs: kept the RB root exec-permission bypass
(ruid/euid != 0 gate, Linux-matching behavior).
- Cargo.lock: syn 2.0.118 -> 2.0.119 (upstream).
Verified: repo cook relibc --force-rebuild successful;
verify-fork-functions.sh --no-fetch relibc passes;
all 9 forks now pass the gate.
