Fixed: now skipping correct number of values in magnitude buffer

Variable j points to the current location in the magnitude vector.
When decoding a message  (MODES_PREAMBLE_US+msglen)*2 is added to j.
In the loop head j is increased by 1, so one value was skipped.

A few minor additions and bug fixes as detailed below

1) Additional command line option "--net-buffer <n>" to specify the TCP
output buffer size. Default is n=0, which is 64Kb. Specify a value of n
to increase the buffer size according to  Size  = 64Kb * 2^n, so an n of
1 = 128Kb, n=2 is 256Kb etc. n is limited to 7, so the max size is 8Mb.
This option may assist if you have a high number of aircraft being
received, and an unreliable network connection, or if the receiving end
can be busy for an extended time.

2) Bug fix in ppup1090 which prevented the uploading of valid
ModeA/Squawk codes

3) Bug fix per Markus Grab's commit.

Incorrect value for auto-gain

Incorrect value for auto-gain option the Modes.gain is multiplied by 10.
