1. With various (debug and/or tracing?) kernel options enabled it's
possible for 'struct inode' and 'struct super_block' to exceed the
default frame size, leaving errors like this in config.log:
build/conftest.c:116:1: error: the frame size of 1048 bytes is larger
than 1024 bytes [-Werror=frame-larger-than=]
Fix this by removing the frame size warning for config checks
2. Without the correct headers included, it's possible for declarations
to be missed, leaving errors like this in the config.log:
build/conftest.c:131:14: error: ‘struct nameidata’ declared inside
parameter list [-Werror]
Fix this by adding appropriate headers.
Note: Both these issues can result in silent config failures because
the compile failure is taken to mean "this option is not supported by
this kernel" rather than "there's something wrong with the config
test". This can lead to something merely annoying (compile failures) to
something potentially serious (miscompiled or misused kernel primitives
or functions). E.g. the fixes included here resulted in these
additional defines in zfs_config.h with linux v4.14.19:
Also, drive-by whitespace fixes in config/* files which don't mention
"GNU" (those ones look to be imported from elsewhere so leave them
alone).

Historically libblkid support was detected as part of configure
and optionally enabled. This was done because at the time support
for detecting ZFS pool vdevs had just be added to libblkid and
those updated packages were not yet part of many distributions.
This is no longer the case and any reasonably current distribution
will ship a version of libblkid which can detect ZFS pool vdevs.
This patch makes libblkid mandatory at build time and libblkid
the preferred method of scanning for ZFS pools. For distributions
which include a modern version of libblkid there is no change in
behavior. Explicitly scanning the default search paths is still
supported and can be enabled with the '-s' command line option.
Additionally making libblkid mandatory means that the 'zpool create'
command can reliably detect if a specified device has an existing
non-ZFS filesystem (ext4, xfs) and print a warning.

libblkid support is dormant because the autotools check is broken and
liblkid identifies ZFS vdevs as "zfs_member", not "zfs". We fix that
with a few changes:
First, we fix the libblkid autotools check to do a few things:
1. Make a 64MB file, which is the minimum size ZFS permits.
2. Make 4 fake uberblock entries to make libblkid's check succeed.
3. Return 0 upon success to make autotools use the success case.
4. Include stdlib.h to avoid implicit declration of free().
5. Check for "zfs_member", not "zfs"
6. Make --with-blkid disable autotools check (avoids Gentoo sandbox violation)
7. Pass '-lblkid' correctly using LIBS not LDFLAGS.
Second, we change the libblkid support to scan for "zfs_member", not
"zfs".
This makes --with-blkid work on Gentoo.

This change updates the AC_LANG_PROGRAM autoconf macro invocations to be
wrapped in quotes. As of autoconf version 2.68, the quotes are necessary
to prevent warnings from appearing. Specifically, the autoconf v2.68
Forward Porting Notes specifies:
It is important to note that you need to ensure that the call to
AC_LANG_SOURCE is quoted and not expanded, otherwise that will
cause the warning to appear nonetheless.
Finally, because of the additional quoting we can drop the extra
quotas used by the ZFS_AC_CONFIG_USER_STACK_GUARD autoconf check.

Add autoconf style build infrastructure to the ZFS tree. This
includes autogen.sh, configure.ac, m4 macros, some scripts/*,
and makefiles for all the core ZFS components.
