LibC/DynamicLoader: Add support for dynamically loaded TLS

Previously I failed to dlopen if any of the objects contained TLS

Kernel: Optimize futexes
...
Add support for processor local futexes. These work the exact same way
as global ones, but only lock a process specific lock and use a process
specific hash map.
Also reduce the time futex lock is held. There was no need to hold the
global lock while validating addresses in the process' address space.

Kernel/LibC: Replace SYS_{GET,SET}_TLS with SYS_{SET,GET}_{FS,GS}BASE

LibC: Make pthread_barrier safe

It used to deadlock and it was not safe if more threads than the target
were attempting to wait on it.

DynamicLoader: Fix TLS on 32 bit platform
...
There were two problems with my previous implementation
- TLS was not allocated if nothing used it. There is a fallback
initialization in _init_libc, but this was not enough if one of the
init functions tried to access errno.
- __tls_get_addr was not resolved. If __tls_get_addr was called through
a plt entry, everything would just break :(

LibC: Cleanup pthread code and add some pthread_attr functions

errno, pthread cleanup and pthread id are now stored in uthread. This
allows using these without TLS

LibC: Implement dummy pthread_attr_{get,set}detachstate

detached threads are not yet supported, but this allows implementation
to make sure threads are joinable.

This is yet another bad sched_yield implementation :D

LibC: Implement basic pthread mutexes
...
This implementation is just calling sched_yield if it could not get
mutex. This is not optimal as it does not allow the CPU to idle, but it
works for now :)
Also I did not test this code at all, but it feels correct :D

LibC: Use BAN::atomic_* functions in pthread spinlock
...
This allows us not to reinterpret_cast pthread_spin_t to
BAN::Atomic<pthread_spin_t> which is much better :)

For some reason this does not work on 32 bit version, so it is disabled
on that platform. I'll have to look into it later to find the bug :)
