GhostFS
-------

- Rename gmount to ghostfs_mount and add ghostfs_create. So ghostfs_mount will
only be responsible for mounting, and ghostfs_create only for creating files
with a given url and additional parameters such as attributes. [DONE]
- Use symlink for file creation instead of using touch + setfattr, the latter
being used to set url.
- Add support to ftp protocol.
- Add support to scp protocol.
- Add support to directories.
- GhostFS isn't persistent, so let's add a config file that will contain
the file system structure. This config file will be passed to ghostfs_mount
which in turn will reconstruct the structure based on the information stored.
    Example of config file:
    { .name=/file, .url=example.com/file, .attributes = { {key, value} } }
    { .name=/dir/file2, .url=example.com/file2, .attributes = {} }
- Add shrinker ability to cache. Cache will be shrunk if more than 80% of
system memory is being used. Consider using mmap/munmap for better efficiency
of a shrink. Allocation wouldn't go through LIBC.


GhostFS plugins
----------------

- Add support to extern drivers written in other languages:

[X] Python
[ ] Perl
[ ] Java
[ ] Lua
[ ] Ruby

- Add support to sqlite protocol.
    - sqlite protocol will be about querying a sqlite database, and the return
    value will be available by reading the file.
    - attribute query will be used to store the query
    - we may need additional attributes such as password to access database
    content.
    - when file size is needed, we will have to perform the query, cache it
    and then return the size of the query result as the file size.

- Add support to other database protocols:

[ ] MySQL
[ ] PostgreSQL
[ ] Cassandra
[ ] Redis
[ ] ScyllaDB
[ ] mongoDB
[ ] Parse
[ ] FirebirdSQL
