Arvind Sankar c0673571d0 Switch off -Wmissing-prototypes for libgcc math functions
spl-generic.c defines some of the libgcc integer library functions on
32-bit. Don't bother checking -Wmissing-prototypes since nothing should
directly call these functions from C code.

Include the header with prototypes in the file that provides definitions
as well, to catch any mismatch between prototype and definition.

Arvind Sankar 65c7cc49bf Mark functions as static
Mark functions used only in the same translation unit as static. This
only includes functions that do not have a prototype in a header file
either.

Ubuntu 7cf1fe6331 cppcheck: (error) Uninitialized variable
As of cppcheck 1.82 warnings are issued when using the list_for_each_*
functions with an uninitialized variable.  Functionally, this is fine
but to resolve the warning initialize these variables.

Matthew Macy da92d5cbb3 Add zfs_file_* interface, remove vnodes
Provide a common zfs_file_* interface which can be implemented on all 
platforms to perform normal file access from either the kernel module
or the libzpool library.

This allows all non-portable vnode_t usage in the common code to be 
replaced by the new portable zfs_file_t.  The associated vnode and
kobj compatibility functions, types, and macros have been removed
from the SPL.  Moving forward, vnodes should only be used in platform
specific code when provided by the native operating system.

Matthew Macy 4a2ed90013 Wrap Linux module macros
MODULE_VERSION is already defined on FreeBSD. Wrap all of the
used MODULE_* macros for the sake of consistency and portability.

Add a user space noop version to reduce the need for _KERNEL ifdefs.

Matthew Macy bced7e3aaa OpenZFS restructuring - move platform specific sources
Move platform specific Linux source under module/os/linux/
and update the build system accordingly.  Additional code
restructuring will follow to make the common code fully
