Revert "keep a running count of buffer allocations so freed buffers aren't queued twice"

This reverts commit 6a60cd5190da1573b1f39f44d30f95edab2c0a5c.

This has been implemented by gomspace now using a better approach.
Revert "Moved csp_conn.h to the global include directory."

This reverts commit 250beda7a68dd2abd63d4e16d05f755528c316f2.

This was just a quick hack to make some data structures available so we
could check how many connections were open at any given time.
Revert "Added a global flag set when transmission of kiss frames is happening."

This reverts commit 20e785e33e5682931f1a96a0e941b9169cdc0ae6.

Horrendous hack, unsafe global value to check if a kiss frame was being
transmitted so we could stop normal I/O functions to print stuff out in
the middle of it.
Revert "added a 'multikiss' interface, supporting up to 2 KISS interfaces on one node:"

This reverts commit cd523754abdbab451136c05b192ab87a5f0ca2a3.

Removes our hackish multikiss implementation. Gomspace already fixed
this need in the newer versions of libcsp.

Upgraded astrodev interface to thread-safe architecture and internal API changes.

We need to be sure std=c99 is always set.
