Kernel/LibC: Replace SYS_{GET,SET}_TLS with SYS_{SET,GET}_{FS,GS}BASE
...
This allows userspace to use both registers

Kernel: Implement proper memory region splitting
...
Memory regions are now splitted when they get munmapped, mprotected, or
mmapped with MAP_FIXED. This is used by couple of ports, and without
this we were just leaking up memory or straight up crashing programs.

Kernel/LibC: Implement {recv,send}msg as syscalls
...
This also removes the now old recvfrom and sendto syscalls. These are
now implemented as wrappers around recvmsg and sendmsg.
Also replace unnecessary spinlocks from unix socket with mutexes

Kernel: Don't crash if Ext2 filesystem doing too many fileops
...
I had a hardlimit of 10 block buffers and if they ran out, the kernel
would crash. this patchs increases the number of buffers to 16 and
removes the crash condition when they run out :D

Kernel: Allow file backed mapping be larger than inode size

This is only allowed if the mapping does **not** exceed a page boundary.
Some port was doing an exactly two-page-mapping on a file that was one

Kernel: Zero initialize Processors

This moves processor array to .bss reducing data size by 8192 bytes :)
This needed GCC updated to 15.2.0 because of an internal compiler error
I found :)

This definitely will break stuff but I don't think anything depends on

This WILL get fixed soon (I hope :D)

Some stuff tries to use shared futexes so make them all shared. Private
futexes would be faster as they are process specific but supporting both

Kernel: Fix termios and enter key handling
...
Enter key now produces expected \r which gets converted to \n by default
by the ICRNL input flag.
Also input flags are now handled always, not just when ICANON is set.
I don't know why I though ICANON should disable input handling
