Get rid of lanplus-specific yet very generic in nature
lanplus_swap() function that unconditionally swaps bytes
in an arbitrary byte array. Move it to helper module and
add two conditionally working interfaces to it:
- array_ntoh() for network (BE) to host conversion, and
- array_letoh() for ipmi (LE) to host conversion.
The added functions will only perform byte swapping if
the target architecture differs in endianness from the
data source. array_ntoh() will only do swap on LE machines,
while array_letoh() will only do it on BE ones.
These functions are introduced for future use in other
places of ipmitool.
Partially resolvesipmitool/ipmitool#26

There are lots of feature test macros like _POSIX_SOURCE,
_BSD_SOURCE, etc. chaotically placed at the beginning of
multiple files without apparent reason, sometime purely
erroneously.
This commit removes them all for the sake of cleaner code.
No new warnings are added due to that at least for gcc 5.4
on Linux with glibc 2.23.
Commit adds macros and #include in order to bring down the number of `warning:
implicit declaration of function 'X' [-Wimplicit-function-declaration]`
warnings.
Despite the fact we could leave this up to IPMI stack, we won't do that.
Therefore, is_ipmi_user_priv_limit() is added and user provided value checked.
