847208cd8a util: Fix build on FreeBSD by avoiding NSS_BUFLEN_PASSWD 
NSS_BUFLEN_PASSWD is not defined on FreeBSD.  Use
sysconf(_SC_GETPW_R_SIZE_MAX) instead, as per POSIX.

Use a dynamically allocated buffer instead of trying to cram all of
the logic into the declarations.  This will come in useful later
anyway.

922bce2668 util: Simplify input validation 
It appears that snprintf(3) is being used for input validation.
However, this seems like overkill because it causes szPath to be
copied an extra time.  The mostly likely protections being sought
here, according to https://cwe.mitre.org/data/definitions/20.html,
look to be DoS attacks involving CPU and memory usage.  A simpler
check that uses strnlen(3) can mitigate against both of these and is
simpler.

de46ad9084 lib/util use modules_path(), data_path() and shlib_ext() from source3 
This brings these helpful utility functions in common, as they are not
based on either loadparm system.

(The 'modules dir' parameter from Samba4 will shortly be removed, so
there is no loss in functionality)
