Simplify logic to calculate the BT/system clock latency
...
This is only a cosmetic change. Using a while loop
we avoid direct manipulation of counter loop variable
when error happens reading the BT clock.

Fix potential lockup while finding latency
...
This patch fixes a potential infinite loop while finding the
BT/system clock read latency. If the adapter is removed exactly
at that moment, BT clock simply can't be read and it must quit.
This is handled as a temporary failure (if a new connection is
made, adapter is probably in place again).

Fixes several small issues found with PTS testing
...
1. BT clock reading is retried a few times upon failure. Temporary
failures seem to be common (at least in a VM environment) and
CSP needs to deal with it more gracefully.
2. Do not read local BT clock if ioctl() fails; fail and let the
higher-level function to retry. No clock is better than the wrong
one.
3. Add a field to SyncLeadTime in capabilities struct, since this
is checked by PTS and a better/clearer estimate is needed
throughout the code (see below).
4. Make sure every scheduling is delayed by SyncLeadTime. PTS does
not like to receive a message before this.
5. Added a more conservative (and bigger) estimate of SyncLeadTime
(PTS insists about receiving immediate responses within it).
6. Sync Indication is immediately sent in two ocasions: right after
a sync set, and right after sync set response (and every "n"
seconds after that, depending on required accuracy).
7. Timestamp resolution is set to 1 when operating system call
yields resolution = 0.

Added CSP enabling/disabling API; GError argument positioning
...
MCAP stack wakes up with CSP disabled. It must be enabled
explicitly. MCL connections created prior to CSP enabling
won't be CSP-capable; only new MCLs will.
GError pointer is by convention the last parameter in request functions.

Change the way that connections are rejected
...
MCAP requires that connections are refused at L2CAP layer using a
connection response "Connection refused -no resources available".
By default, deferred connections in BlueZ are rejected using the
code "Connection refused - security block".
As in BlueZ is not possible to reject the defer connection with
this response code. This patch don't defer the connection and
close it immediately. This is also a valid behaviour for rejecting
connections in MCAP.
