test/fuzz: add some applications, add an experimental multi-packet mode

Browse Source 
The experimental multi-packet mode splits input bytes depending on a length
decoded from the first 2 bytes and does that until the end of input.
To use this mode, compile with "make D=-DLWIP_FUZZ_MULTI_PACKET"

Just running make will produce the test program.
Running make with parameter 'D=-DLWIP_FUZZ_MULTI_PACKET' will produce a binary
that parses the input data as multiple packets (experimental!).
Then run afl with:
afl-fuzz -i inputs/<INPUT> -o output ./lwip_fuzz
