25f6579016 Bluetooth: Move all bt_conn related APIs to conn.h
To have some proper split of conn.h and bluetooth.h APIs make sure all
bt_conn related ones are in conn.h. This also helps avoid forward
declarations for some upcoming patches where we need bluetooth.h
defines from within conn.h.

3c47e9515c Bluetooth: Update advertising API
Update the advertising API according to what has recently been
discussed and agreed upon.

Naming-wise the most important change is the removal of "EIR" which
was confusing since this is mainly used with LE at the moment. The
Core Specification Supplement consistently uses the generic terms data
and data type to describe what we're dealing with here, so the new
names are bt_data and BT_DATA.

Another change is to detach the actual data from the struct by
converting it from an array to a pointer. This is not only essential
for supporting BR/EDR (which has a different length) but to also
minimize memory usage.

Another change is to require the caller of bt_le_adv_start() to
provide the array lengths of the ad and sd paramters. This way we
don't have to have the empty (8-byte) element at the end of each
array.

Lastly, the bt_le_adv_start() logic is slightly modified so that it
will always clear the respective data if necessary. Previously the
user might have been left with a previous callers data if it passed
NULL to the API.

8ff6884077 Bluetooth: Fix buffer overflow with ACL fragments
The fragments we create should not be greater than the connection ACL
MTU (which the code already does correctly) but they can also not be
greater than the buffer has room for data. Fix this by taking the
minimum of the connection MTU and the buffer tail room.

7160c9c95e Bluetooth: Move BT_STACK definitions to log.h
BT_STACK depends on BT_STACK_DEBUG_EXTRA, therefore moving it there.
It also allows to use BT_STACK in drivers, at the moment only
Bluetooth stack uses it.

7e1e124b8c Bluetooth: SMP: Separate legacy pairing code
All legacy pairing code is now separated in dedicated helper functions
(with 'legacy' prefix). Main code flow is LE SC oriented and legacy
pairing is always handled as exception from LE SC code:

if (!atomic_test_bit(&smp->flags, SMP_FLAG_SC)) {
  return legacy_foo(smp);
}

This is in preparation for enabling LE SC only mode.
