Adds file_lock() and file_unlock() to change the lock state of a file.
file_new() is removed, the only way to create a file is with
file_get_by_tag() which will return an empty newly allocated file if
none can be found.
file_add_slice() is added to add slices to a file, one by one.
With this can multiple threads try to load a TA at once, the first one
taking the lock will add all the slices to the file.
The code in user_ta.c and elf_load.c using the <file.h> interface can
be optimized to allow more operations in parallel.
