This removes the flow encryption option (cypher_s) from the qosspec.
The configuration file is configured in the security options (default
/etc/ouroboros/security/). For this poc, encryption can be disabled
client or server side by putting an enc.cfg file. If that file is
present in the client folder, the client will require encryption. If
that file is present on the server side, the server will require
encryption and reject non-encrypted flows.
Encryption is now configured outside of any application control.
Example: /etc/ouroboros/security/client/oping/enc.cfg exists:
irmd(II): Encryption enabled for oping.
irmd(DB): File /etc/ouroboros/security/client/oping/crt.pem does not exist.
irmd(II): No security info for oping.
irmd(DB): Generated ephemeral keys for 87474.

irmd/oap(PP): Data: <none>

irmd(WW): Encryption required but no key provided.
The server side will pass the ECRYPT to the client:
$ oping -l
Ouroboros ping server started.
Failed to accept flow: -1008
$ oping -n oping -c 1
Failed to allocate flow: -1008.
Encryption on flows can now be changed at runtime without needing to
touch/reconfigure/restart the process.
Note: The ECRYPT result is passed on via the flow allocator responses
through the IPCP (discovered/fixed some endianness issues), but the
reason for rejecting the flow can be considered N+1 information... We
may move that information up into the OAP header at some point.

This adds initial implementation of peer authentication as part of
flow allocation. If credentials are not provided, this will be
accepted and logged as info that the flow is not authenticated.
Certificates and keys are passed as .pem files. The key file should
not be encrypted, else the IRMd will open a prompt for the password.
The default location for these .pem files is in
/etc/ouroboros/security. It is strongly recommended to make this
directory only accessible to root.

Trusted root CA certificates go in the /cacert directory, untrusted
certificates for signature verification go in the /untrusted
directory. The IRMd will load these certificates at boot. The IRMd
will look for certificates in the /client and /server directories. For
each name a subdirectory can be added and the credentials in that
directory are used to sign the OAP header for flows at flow_alloc() on
the client side and flow_accept() on the server side.
These defaults can be changed at build time using the following
variables (in alphabetical order):
OUROBOROS_CA_CRT_DIR /etc/ouroboros/security/cacert
OUROBOROS_CLI_CRT_DIR /etc/ouroboros/security/client
OUROBOROS_SECURITY_DIR /etc/ouroboros/security
OUROBOROS_SRV_CRT_DIR /etc/ouroboros/security/server
OUROBOROS_UNTRUSTED_DIR /etc/ouroboros/security/untrusted
The directories for the names can also be configured at IRMd boot
using the configuraton file and at runtime when a name is created
using the "irm name create" CLI tool. The user needs to have
permissions to access the keyfile and certificate when specifying the
paths with the "irm name create" CLI tool.

This makes the IRMd a bit simpler, and we only need to do the lookup
to resolve the name for a hash on the server side only once. The
logging is also symmetric now:
irmd(II): Allocating flow for 93317 to unicast.1.
irmd(II): Flow request arrived for unicast.1.

This is a full revision of the IRMd internal implementation.
The registry is now a proper subcomponent managing its own internal
lock (a single mutex). Some tests are added for the registry and its
data structures. Some macros for tests are added in <ouroboros/test.h>.
Flow allocation is now more symmetric between the client side (alloc)
and server size (accept). Each will create a flow in pending state
(ALLOC_PENDING/ACCEPT_PENDING) that is potentially fulfilled by an
IPCP using respond_alloc and respond_accept primitives. Deallocation
is split in flow_dealloc (application side) and ipcp_flow_dealloc
(IPCP side) to get the flow in DEALLOC_PENDING and DEALLOCATED state.
Cleanup of failed flow allocation is now properly handled instead of
relying on the sanitizer thread. The new sanitizer only needs to
monitor crashed processes.
On shutdown, the IRMd will now detect hanging processes and SIGKILL
them and clean up their fuse mountpoints if needed.
A lot of other things have been cleaned up and shuffled around a bit.

Some definitions/enums were different between the library and IRMd
(flow_state, ipcp_state). This moves them to common ground.

Rename internal data structures so it's clear that they are the IRMd
representation of these objects for management purposes.
Split functionality for these objects off and and move them to their
own source files.
Rename internal functions of the IRMd to reflect this, with some small
refactoring.
