This partially reverts commit 8005ca4 by moving the strlcat()
and strlcpy() compatibility implementations back to their original
location.
In addition, these two functions were added to the AC_CHECK_FUNCS
macro. When these functions are available from the C library,
HAVE_STRLCAT and HAVE_STRLCPY will be defined and library version
used. Otherwise the compatibility version is built.

Move strlcat() and strlcpy() from .c source files in to the libspl
string.h header. By changing these compatibility functions to static
inline functions they can included as needed without requiring linking
with the libspl.so library.
Remove strnlen() which is barely used in the source, and has been
provided by glibc since v2.10.
Finally, convert four instances of strncpy() to strlcpy() in
libzfs_input_check.c which were causing build warnings when compiling
with gcc 8.2.1. For example:
libzfs_input_check.c: In function ‘zfs_destroy’:
libzfs_input_check.c:651:9: error: ‘strncpy’ specified bound \
4096 equals destination size [-Werror=stringop-truncation]
(void) strncpy(zc.zc_name, dataset, sizeof (zc.zc_name));

The vast majority of these changes are in Linux specific code.
They are the result of not having an automated style checker to
validate the code when it was originally written. Others were
caused when the common code was slightly adjusted for Linux.
This patch contains no functional changes. It only refreshes
the code to conform to style guide.
Everyone submitting patches for inclusion upstream should now
run 'make checkstyle' and resolve any warning prior to opening
a pull request. The automated builders have been updated to
fail a build if when 'make checkstyle' detects an issue.

All changes needed for the libspl layer. This includes modifications
to files directly copied from OpenSolaris and the addition of new
files needed to fill in the gaps.
