Fill out the stat structure so that the nanosecond resolution support is
always available. There is a small code size increase for a few ports
(three additional assignments in xstatconv), but otherwise everything
should remain the same.
While we're here, punt __old_kernel_stat from the few headers that still
define it as it is unused in uClibc and causes compile errors after these
nanosecond changes.

The sbrk() function can be used to merely query sizes and for that, no-mmu
works the same as mmu. It can also sometimes increase data segments on
no-mmu systems provided the trailing memory is free. So, there is no real
reason to exclude this function for no-mmu ports.

The entry symbol is __start rather than __dl_boot. While in the past this
was silently ignored, now with common code checking the _start symbol in C
code, we end up with link errors:

ldso/ldso/ldso.c:(.text+0x2b30): undefined reference to `__start'

The dlpi_addr isn't a simple Elf_Addr type for FDPIC systems, so we can't
just assign 0 to it to initialize.

The Blackfin port hasn't been compiling cleanly, so this typo was missed

The order of attributes in a function definition matters and in a few
places in the Blackfin code, it was being applied to the return type
instead of the function itself.

The Blackfin port never defined elf_machine_load_address() because the one
place this code is called never matters to us. But without it, common code
likes to hit a build failure, so stub it out.

The force shareable code missed a spot of using the DL_RELOC_ADDR()

The majority of the byteswap functions are the same across all arches, so
setup a common header to provide definitions if they don't exist. This
allows arches to override only the ones they actually want to implement
with inline assembly.

Undo my old mistake. I added UCLIBC_INTERNAL define,
but later I realized _LIBC is doing exactly the same thing.
This change converts all usages of UCLIBC_INTERNAL to _LIBC,
removing all instances of UCLIBC_INTERNAL.

This syncs the dirent related functions with the glibc behavior -- rather
than take void pointers everywhere, make the struct dirent pointers
explicit in the API. After all, the functions themselves will cast the
pointers to a dirent structure, so if it isn't as expected, people will
crash.

We want to let malloc() and friends be overridable at runtime so that apps
can insert their own implementation (think debugging, specialized setups,
etc...). That means that C library functions that return allocated memory
have to go through the normal malloc() symbol as well as the external code
is the one who will be calling free().
