Add typed request return value that indicates request is OK or requires endpoint STALL.
...
Changed vendor request to a lookup table, instead of an ever-growing switch statement.

Add USB control of LPF baseband filter.
...
Add max2837_set_lpf_bandwidth() function to choose available LPF filter bandwidth based on bandwidth in Hz.
Change configuration of MAX2837 to set LPF_EN and FT at max2837_setup(), not in max2837_rx() or max2837_tx() (which was overriding prior filter configuration).

Factor out sample_rate_set() from cpu_clock_init().
...
Implement switching between several supported sampling rates for Jellybean and Jawbreaker.
Commit bits of the Si5351C USB request support that I apparently missed in a prior commit.

Oops! Forgot to change MAX2837 mode from RX to TX when transceiver mode is changed.
...
Initialize MAX5864 earlier, in "transceiver" mode (where both ADC and DAC are active), and then shift SSP1 into MAX2837 mode and leave it there, for faster tuning and RX/TX switching.

Return of the hand-optimized assembly for SGPIO read and write interrupt.
...
Reset only the one SGPIO slice flag that is actually causing the interrupt.

Move USB SET_CONFIGURATION-time initialization of SGPIO and bulk endpoints into a separate function.
...
Initialize transceiver mode at SET_CONFIGURATION time.
Provide switching of transceiver mode via vendor request.
Provide read/write access to MAX2837 registers via vendor requests.
Python utility to dump MAX2837 registers.
Python utility to switch transceiver RX/TX mode.

RX and TX sample buffer loops turned out to be the same, so they're consolidated.

Consolidated two "deep" SGPIO configuration functions into one, qualified by transceiver mode (RX or TX). 95-ish % of the code was common.

Moved transceiver_mode_t to hackrf_core.h.
...
Changed transceiver_mode to volatile, since it's liable to be accessed at interrupt time.

Reworked USB code to pump SGPIO with an interrupt.
...
Relocated USB buffers to be split across two AHB memory regions, so that USB endpoint priming doesn't choke SGPIO transfers.
Added code to configure 2.4GHz front-end.
Changed USB and SGPIO priority levels (probably unnecessary because sample corruption was due to USB priming bursts).

Hot steaming pile of in-progress USB test code. Eventually, this will morph into a proper stack. But first, to "make it work".

USB performance test firmware project. It does absolutely nothing to start with, but at least the Makefile I just checked in won't blow up! :-)
