For BE architectures there is one significant difference
in comparison with time64 support for little-endian
architectures like ARMv7.
The difference is that we strictly need to pass two 64bit
values to system calls because Linux Kernel internally uses
`struct __kernel_timespec` and similar, which consists of two
64bit fields.
For this reason many files have been changed to convert
pointers to timespec-family structures (mixed of 64bit and 32bit values)
to the pointer of the similar but 64bit-only structures
for using as system calls args.
This is general prerequisite for any BE architecture.

Note: _PATH_UTMPX == _PATH_UTMP and the utmp struct is identical to the
utmpx struct so this only changes the external API entrypoints and NOT
the underlying data source.
This saves about 500b (~1300b from previously ~1950) while at it.

Partially reverts "parser_config.[ch]: remove duplicated hidden functions"
There's a namespace collision for config_{open,close,read} functions
between uClibc and Busybox. Callers in uClibc and busybox need to call
their local variants. In case of static linking, both the variants need
to be pulled in the final executable.
Turns out that the existing hidden attribute is not enough for static
linked Busybox where the linker treats these symbols as duplicate and
pulls in only the local (Busybox's own) variants in the final link.
This obviously causes the uClibc callers to crap out at runtime.
This can be fixed by restoring the libc_hidden_proto() annotation
which causes the libc variants to be aliased with __GI_ prefix thus
making both the symbols distinct from linker's perspective.
This issue was found with ARC gcc 4.8 + uClibc trunk.
I can confirm the same thing with ARM uClibc buildroot build (when
switching to uClibc daily snapshot).
All the credit for debugging the issue goes to Anton,Joern and Jeremy -
I simply found the cure :-)

Our impl has diverged from busybox' so make sure nobody else uses it.
