Merge large page support code.
This code was originally written by Andreas Dillier as a deliverable for his
Bachelor thesis at ETH Zurich in 2013. Simon Gerber then fixed and extended
the implementation of large page support while employed by HP Labs in summer
2014.

x86_64: kernel: cleanup of page table dumping.
paging_dump_tables now finds the first pml4 entry of the "identity"-mapped RAM
and stops displaying page tables for all of it based on the offset configured
in /kernel/include/arch/x86_64/offset_targets.h.
We now also properly cast the base addresses of large/huge pages to genpaddr_t
before bitshifting to avoid sign extending. This is necessary because
bitfield fields are implicitly plain ints.

x86_64: pmap: removed support code for mixed-size mappings.
Mixed-size mappings (e.g. composing a mapping from 4k and 2M pages) don't work
on x86 unless the physical and virtual addresses have matching alignments (a
2M mapping needs both a 2M aligned virtual and physical address). Thus we
don't support this case in the default library OS.
The kernel doesn't care though and you can roll your own system where you
allocate physical memory that matches the alignment so that the first 2M
aligned virtual address lands on a 2M aligned physical address.

posixcompat: make pthread_once a wrapper over the version in libbarrelfish
Summary:
Both the pthread and native versions now share a single common
implementation (added in D9). The new approach should also be faster
since it avoids a full mutex and instead only has to consult the
per-thread epoch on the common path. I should note, I have not run
any benchmarks to confirm this and may be wrong.
Test Plan: Compiles but have not validated more thoroughly.

thread: add support for one-time global initialization
Summary:
This is an action that needs to be coordinated globally but the implementation
doesn't have to be as pessimistic. The initialization function is only run
once and the common case is checking whether it has already been run. The idea
here is to have a fast and slow path and let each thread use a locally cached
value.
Test Plan:
Tested with the small code snippet below. Initialization function ran
correctly (and only once). For correctness of the locking scheme I
defer to the proposal document referred to in the header comment of
`lib/barrelfish/thread_once.c`.
lang=c
#include <barrelfish/threads.h>
static thread_once_t init = THREAD_ONCE_INIT;
static void init_func(void) {
printf("init\n");
}
int main() {
thread_once(&init, init_func);
printf("Hello World\n");
thread_once(&init, init_func);
return 0;
}

Rename struct slab_alloc to struct slab_allocator.
We have a function with the following signature:
void *slab_alloc(struct slab_alloc *);
which produces the following error message with g++:
error: ‘void* slab_alloc(slab_alloc*)’ hides constructor for ‘struct
slab_alloc’ [-Werror=shadow]
The two easy ways out are 1) renaming the function or 2) renaming the struct.
For clarity (and consistency with malloc and co) I've chosen to rename the
struct to "struct slab_allocator".
