moved the handling of SFTP handles to new linked list code

Browse Source 
Each SFTP file handle is now handled by the "mother-struct"
using the generic linked list functions. The goal is to move
all custom linked list code to use this set of functions.

I also moved the list declarations to the misc.h where they
belong and made misc.h no longer include libssh2_priv.h itself
since now libssh2_priv.h needs misc.h...

In misc.c I added a #if 0'ed _libssh2_list_insert() function
because I ended up writing one, and I believe we may need it here
too once we move over more stuff to use the _libssh2_list* family.
