[PATCH 0/3] Add READ_BLOB support to attrib-server

The following patches were cretated off of the working bluez tip at git.kernel.org as of:

commit f0411254277e6c2273d32379e4a2d3742ee05e55

    Update NREC callback code to originally intended v2 state


Patch 1 adds the default MTU for L2CAP based ATT connections (48) and
modifies the usages for consistency.  This is important when segmenting
long attribute over multiple transactions, because remote clients will
typically decide wether to issue subsequent READ_BLOB request based on wether
the prior read filled the entire MTU.  This explicitely does not address
situations where a larger MTU than the defaults (23 and 48) are used, but
in practice, there is no evidence that they exist at this time.

Patch 2 is some maintanence to fix the attrib-server to correctly indicate
the end of the service range, if a primary or secondary service contains
nothing but the service declaration.  This can be seen prior to this patch
in attrib-server.c in the GATT_PRIM_SVC_UUID definition which sent a service
range of 0x0010 - 0x0006 instead of 0x0010 - 0x0010.

Patch 3 completes the implementation.  It can be tested on the current example
server by reading attribute 0x0214, which caontains a 25 octet string.
