Unify the comparison idioms use.
Always use `if(!strcmp())` for "if string equals"
and `if(strcmp())` for "if string is not equal".
Never use `== 0` and `!= 0` with `strcmp()`.
Minor reformatting of the code immediately surrounding the
refactored lines.

Clean up use of strcmp/strncmp/strncasecmp for command line arguments.
Never use anything but `strcmp()` unless absolutely neccessary.
Partialy resolvesipmitool/ipmitool#104
Remove all direct comparisons to 'NULL' for pointers.
Replace them with boolean-like 'if (ptr)' and 'if (!ptr)'.
This makes conditions shorter and easier to read.

Make code better readable by replacing `if (rsp->ccode > 0)`
and 'if (rsp->ccode != 0)' with just `if (rsp->ccode)` as
rsp->ccode is anyway an unsigned byte and can't be negative.
Also replace 'if (rsp->ccode == 0)' with 'if (!rsp->ccode)'.
All these changes make lines shorter and easier to read as
a non-zero ccode is an indication of some failure, and so !ccode
naturally reads as 'no error'.

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.
