vasilito ae03a7e60b kernel: Linux-compatible /proc/[pid]/stat format 
Implements proper /proc/[pid]/stat output matching Linux fs/proc/array.c format:

- utime/stime: separate user/kernel CPU time accounting in context switch
- pgrp/session/start_time: process group, session, boot-time start
- proc_rss(): Resident Set Size from page table grant walker
- num_threads: thread-group counting via owner_proc_id filter
- nice: derived from priority (prio/2 - 20)
- proc_stat_line(): proper 52-field /proc/[pid]/stat format
- proc_status_text(): VmSize/VmRSS in kB

Infrastructure:
- require_zero_offset(): EINVAL for non-zero read/write offsets
- validate_kfmap_flags(): KFMAP flag validation (MAP_SHARED/PRIVATE)
- ContextHandle::Ctx: atomic FullContextRegs save/restore
- kwriteoff: offset parameter for regs/ctx/attr/start writes
- try_stop_context: preserve HardBlocked::NotYetStarted status on restore

- Add SYS_OPENAT/SYS_DUP aliases in local syscall fork for upstream 0.9.0 renamed constants.

- Cast FADT_MIN_SIZE_ACPI_2_0 to u32 to match sdt.length() return type.

- Keep Cargo.lock based on upstream master with only redox_syscall sourced from local fork.

R Aadarsh f8bc19747a Make necessary changes to the kernel in order for relibc to support posix_spawn and posix_spawnp 
* `syscall::sendfd`, now, when called with a `ContextHandle::FileTable` adds the fd to the filetable removing it from the calling process's filetable

* Files can now be added to, removed from another process, and can be duplicated using `ProcScheme::kcall`

* Files of another process with the flag O_CLOEXEC can now be closed by using `kcall`
