Denis Kenzior 9ed01bfecd Refactor: Simplify parsing logic 
It isn't actually necessary to check the basic command prefixes, if the
extended prefix doesn't match we try to parse it like a basic command.
That one does the same exact check anyway.  If that fails, then this is
not a recognized command line anyway.

Zhenhua Zhang 3d4af3eee6 Add framework of server parser 
a. The parser fetch and parse one command per loop. The prefix is
the command prefix without parameter. For example, the prefix of
"AT+CLIP=1" is "+CLIP".

b. Search registered notification node in command_list. Invoke the
callback if found.

c. Termiate the execution if the result is an error. Otherwise,
parse next command.

Zhenhua Zhang 2a58101807 Fix change state immediately when meet the slash 
According to V.250 spec section 5.2.4 Repeating a command line, if

command immediately. No need to meet \r.

Zhenhua Zhang df7b1b30dc Add GAtServer basic parsing support 
It's the basic skeleton of GAtServer, including new/shutdown, ref/
unref, received_data/parse_buffer and set_discuss/set_debug.

GAtServer is to emulate the server side of AT conversation. It
complies with V.250 and 27.007 spec to accept AT command like
ATV1, ATE0 and extended command like AT+CLCC. Upper layer could
create customize server to expose TTY, tcp or unix socket to
client side application.
