Switch from __thread to pthread_key_t for fuse_contextlibfuse/pinotree/fuse-improvements/master

This allows to properly cleanup the per-thread context.

* src/fuse_i.h (libfuse_ctx): Remove declaration.
* src/main.c (libfuse_ctx): Remove variable.
(libfuse_ctx_key): New variable.
(fuse_destroy_context): New function.
(fuse_create_key): Likewise.
(fuse_new): Use fuse_get_context instead of libfuse_ctx.
(fuse_get_context): Create fuse_create_key only once.  Allocate a new
struct fuse_context if needed, and return it.
* src/netfs.c (update_context_struct): Use fuse_get_context instead of
libfuse_ctx.
