6da481205b LibTest: Use fstatat() to speed up iterate_directory_recursively() 
Employ the same technique as SpaceAnalyzer to avoid doing full path
resolution in the kernel over an over. Starting each path resolution
from the base of the directory iterator (using its fd) is significantly
faster and reduces test-js runtime by ~3%.

c81b3e1ee3 LibC: Implement strerror_r() 
This implements the XSI-compliant version of strerror_r() - as opposed
to the GNU-specific variant.

The function explicitly saves errno so as to not accidentally change it
with one of the calls to other functions.

6830963321 Kernel: Validate we don't hold s_mm_lock during context switch 
Since `s_mm_lock` is a RecursiveSpinlock, if a kernel thread gets
preempted while accidentally hold the lock during switch_context,
another thread running on the same processor could end up manipulating
the state of the memory manager even though they should not be able to.
It will just bump the recursion count and keep going.

This appears to be the root cause of weird bugs like: #7359
Where page protection magically appears to be wrong during execution.

To avoid these cases lets guard this specific unfortunate case and make
sure it can never go unnoticed ever again.

The assert was Tom's idea to help debug this, so I am going to tag him
as co-author of this commit.

current element matches with the given selector in the :not and act
accordingly.

there are a few initial bytes which specify the encoding that must
be checked and also removed from the final string.

be6e4b6f3c LibPDF: Store indirect value refs in Value objects 
IndirectValueRef is so simple that it can be stored directly in the
Value class instead of being heap allocated.

As the comment in Value says, however, in theory the max bits needed to
store is 48 (16 for the generation index and 32(?) for the object
index), but 32 should be good enough for now. We can increase it to u64
later if necessary.
