Add Hooks for Linux File Operations
The Linux specific file operations have all been located in the file zpl_file.c. These functions primarily rely on the reworked zfs_* functions to do their job. They are also responsible for converting the possible Solaris style error codes to negative Linux errors. This first zpl_* commit also includes a common zpl.h header with minimal entries to register the Linux specific hooks. In also adds all the new zpl_* file to the Makefile.in. This is not a standalone commit, you required the following zpl_* commits.
