redox: implement getrlimit/setrlimit with a per-process limits table (finite RLIMIT_NOFILE)

fix(spawn): install bootstrap fds in child file table
...
The copied child table did not reliably retain the thread and process descriptors at the numbers exported through auxv. Explicitly clone both descriptors into the selected child table before loading the image, and remove the ineffective parent-handle leak.

fix(spawn): leak child thread fd to prevent race with dynamic linker
...
posix_spawn creates a new context and returns its thread fd to the
parent. The kernel currently does not keep a self-reference to the child
context's thread fd, so when the parent closes its handle, the child's
thread object may be destroyed before the dynamic linker reads
AT_REDOX_THR_FD from auxv and opens regs/env. Leak the parent handle
until the kernel is fixed to retain a reference per context.

fix(pipe2): use FILETABLE-aware open/dup to keep kernel/userspace fd tables in sync

relibc: fix pipe2 to use raw syscalls + register_external_fd
...
The previous pipe2 implementation used redox_rt::sys::open() which goes
through the FILETABLE's insert_upper mechanism. This can collide with
the untracked namespace fd (ns_fd) stored in DYNAMIC_PROC_INFO, causing
the kernel to overwrite the namespace fd entry with a pipe scheme root
entry. Subsequent open() calls then resolve to the wrong scheme, and
kdup fails with EBADF because it receives a write-end (odd) ID instead
of a read-end (even) ID.
Fix: bypass the open() function entirely and use raw syscall::openat +
syscall::dup, then register both fds with register_external_fd so the
FILETABLE tracks them correctly.

relibc: remove PIPE_DIAG debug noise, fix F_SETFD arg in pipe2
...
Remove eprintln debug output from pipe2() FdGuard::open error path.
Fix F_SETFD argument: pass flags & O_CLOEXEC instead of write_flags
(which includes O_WRONLY — not an fd flag).

absorb: 27 orphaned relibc patches re-applied (Phase 1.0A)
...
Per local/docs/PATCH-PRESERVATION-AUDIT-2026-07-12.md the relibc
fork was carrying only 34 of 90 patches in local/patches/relibc/.
The other 56 patches' content was silently missing from the fork.
This commit re-applies 27 patches that genuinely still apply
cleanly. Recovery covers:
- eventfd implementation (sys/eventfd.h + eventfd.rs)
- signalfd implementation (sys/signalfd.h + signalfd.rs)
- timerfd implementation (sys/timerfd.h + timerfd.rs)
- bits/eventfd.h header
- spawn() function: cbindgen + stdint fix
- P3-timerfd-cbindgen-fix
- cbindgen language=C fixes for sys/{timerfd,semaphore}
- stdint include chain fixes
- strtold implementation
- dns aaaa getaddrinfo ipv6
- various stack/threading/header threading fixes
- dup3 syscalls
- waitid implementation
- bits/timespec reverse_from
- open_memstream integration
24 files changed.

* Correctly determine argv[0]
...
- If the function called is `posix_spawnp`, and the passed program name **does not** contain a slash, the path is used unmodified, and the path to the directory containing the program on $PATH is prepended to the program's path and assigned to `argv[0]. If the program name **does** contain a slash, the path is absolutised relative to CWD, and assigned to argv[0]
- If the function called is `posix_spawn`, the behaviour is as described above in the case where path contains a slash
