Well, then according to the current filesystem module interface,
what abstraction is supposed I should provide in the HTTP filesystem?
a) A pdf_fsys_t variable initialized at compile time and, therefore,
assuming the internal structure of the pdf_fsys_t type.
b) A set of procedures and a pdf_fsys_impl_s structure, delegating
to the user the work of create/destroy the HTTP filesystem type
from them.
The second. The user then can use the create function to instantiate
a filesystem variable.
