ldelf: support TA ASLR

Adds support in ldelf to load TAs using address space randomization if
CFG_TA_ASLR=y. Works as before with the kernel mode ELF loader with
two exceptions:
- It falls back to disable ASLR for a particular ELF if it fails to map
using ASLR.
- Each ELF is loaded with a randomized number of free pages in front.
These free pages can be reused when loading other ELF permitting
some ELF to become reordered in memory.

core: lockdep: support non-blocking acquire

Adds support for non-blocking lock semantics such as mutex_trylock().
A new function is introduced to instrument this operation:
lockdep_tryacquire(). It should be called when it is known that
ownership of the underlying object has been granted to the caller. It
behaves similarly to lockdep_acquire() in that it does record the call
stack and records that the lock is owned. But it does not create any
dependencies to the locks that are currently owned by the caller. See
"Dynamic Lock Dependency Analysis of Concurrent Systems" [1] section
5.3.
