Kernel: Make pseudo terminals not overwrite old data

If pseudo terminal buffer was filled, old implementation would overwrite
old data. This is bad if producer is capable of producing more data than
consumer can handle.

Kernel: Fix deadlock caused by multithreading
...
This allows multiple threads to concurrently call the most common
blocking syscalls:
- read
- write
- accept
- connect
- sendto
- recv
- pselect
This prevents a dead lock when for example process is waiting on a pipe,
but unable to write to it since process is locked.
This is the beginning of starting to remove processes own lock from
syscall and locking only necessary parts.
