b5b44ce5c8 Fix not dealing with situations with not enough memory 
GAttrib should fail gracefully in situations when it is not able to
allocate memory, not just crash, which is what g_new() does.

30e62c9151 gatttool: add characteristic descriptor discovery support 
The --start/--end options are reused to allow specifying the
starting/ending handles. Both 16-bit and 128-bit UUIDs are
pretty-printed using sdp_uuid2strn() function.

f9778e74d0 Add g_attrib_set_disconnect_function() 
The function set will be called when GAttrib detects that the link
was cut off. This will allow apps to take the proper actions in this
situation.

5d82240f49 Fix alignment access issues during encoding/decoding 
When encoding/decoding PDU fields, we have to be careful and use
alignment safe functions to load/store the values.

These functions will be exported so other parts of the code can reuse
them.

80c5a1887b Fix reading the Characteristic value multiple times 
We only need to read each characteristic value one time, for example,
at the time that try to discover if that characteristic has any descriptor.

f70c6722f0 Fix using the wrong start handle for Desc. Discovery 
When doing the Descriptor Discovery procedure, the wrong starting
handle was being used (the characteristic value handle). This is what
the spec mandates:

"The Attribute Protocol Find Information Request shall be used with the
Starting Handle set to the handle of the specified characteristic value
+ 1 and the Ending Handle set to the ending handle of the specified
characteristic."

97a1889bac Fix memory leaks on g_attrib_unref() 
We must clean up the event list and the command queue when we destroy
GAttrib, it could be that something is still there.

f01213d025 Add support for cancelling commands 
This adds support for cancelling commands. In case the command to be removed
is the first in the queue, cancelling it would cause its ResultFunc to not be
called. In the other cases, it will be removed from the queue.

92d367140b Fix the opcode verification code being too cryptic 
We need to be more specific about what is the expected response opcode
(if any) for each request command and about if some command is already a
response.

84b6027450 Fix memory leaks in gatttool 
Unix channel reference count must be decremented before exiting. Do not
exit main loop on recursive callbacks, thus allowing queued
g_attrib_send() commands to be finished. Free memory allocated for
opt_src/opt_dst.

e43827833a Fix g_attrib_new() to always create a read watcher 
In order to simplify the code we can always add that watcher when GAttrib is
created and ignore the PDU's that aren't expected.

c2b9e70040 Add support for discovering all the descriptors 
All descriptors associated to every characteristic are discovered, which means,
that we know its handle and type. With this information we can later read the
values of the descriptors that we find interesting.

4dc133a198 gatttool: Replace --char-value-read with generic --char-read option 
The new option is useful for reading either characteristic values or
descriptors, which use the same Read Request. This commit also fixes a
few errors related to the handle options.

0e7aa8f0ac Move connection operations to main in gatttool 
The connection operations (do_connect) were moved to main. So, the
internal call to do_connect() were removed and GAttrib structure is
initialized/freed in main. All callbacks receive the GAttrib structure
through the user_data parameter.

to use same spec nomenclature.
