19d3f8cab7 Kernel+LibC: Turn errno codes into a strongly typed enum 
..and allow implicit creation of KResult and KResultOr from ErrnoCode.
This means that kernel functions that return those types can finally
do "return EINVAL;" and it will just work.

There's a handful of functions that still deal with signed integers
that should be converted to return KResults.

64b0d89335 Kernel: Make Process::allocate_region*() return KResultOr<Region*> 
This allows region allocation to return specific errors and we don't
have to assume every failure is an ENOMEM.

fb4993f067 Kernel: Add anonymous files, created with sys$anon_create() 
This patch adds a new AnonymousFile class which is a File backed by
an AnonymousVMObject that can only be mmap'ed and nothing else, really.

I'm hoping that this can become a replacement for shbufs. :^)
