Add diagAbortWithResult, see details: 
- This is a (weak/overridable) function meant to be called when the
  program encounters an unrecoverable error, but it's not fatal enough
  to bring down the entire system with it.
- The default implementation uses svcBreak, passing the result code
  in the user buffer.
- Replaced all usages of fatalThrow with diagAbortWithResult throughout
  the entire library.

virtmem: Major rewrite to support ASLR, see details: 
- Added virtmemLock/Unlock, needed for atomic find-and-map operations
- Added virtmemFindAslr, which looks for a random free area in AslrRegion
  - virtmemReserve still exists for legacy callers who rely on sequential
    allocation in order to avoid race conditions from concurrent uses
- Added virtmemFindStack, which searches within StackRegion instead
  - Removed virtmemReserveStack/FreeStack
- Changed shmem/thread/tmem/codememory-jit to use the new virtmem API
  - Legacy jit still uses virtmemReserve

afe030f08b rwlock: revamp completely (#350) 
Implements rwlockTryReadLock and rwlockTryWriteLock.
Also implements rwlockIsWriteLockHeldByCurrentThread and
rwlockIsOwnedByCurrentThread.

Also re-designs RwLock to have semantics identical to
Nintendo's (nn::os::ReaderWriterLock). The upshot is mostly
that the lock is now fully recursive/write-preferring.
