Kernel: Remove concept of OpenFile
...
This was just RefPtr<OpenFileDescription> and descriptor flags.
Descriptor flags only define O_CLOEXEC, so we can just store fd's
cloexec status in a bitmap rather than separate fields. This cuts down
the size of OpenFileDescriptorSet to basically half!

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

I was not sharing status and offset on fork and I was sharing descriptor
flags on dup/dup2

to be using.
