Move the sysfs tests for Maple out of unix_get_maple_path() and into a
new linux_get_maple_path(). This prevents unnecessary probing for a
nonexistent /sys on e.g. OS X.

Adds a function to lookup the USB vendor & product id from
the udev info in the sysfs tree. This removes invalid choices
and reduces user queries for the correct ttyACM device.

Instead, derive -march and -mcpu from the target MCU in
target-config.mk. Also (on STM32F4) add the necessary floating point
flags. The CodeSourcery toolchains don't support these, so we'll need
to prepare alternative toolchains when F4 support is official.

We'll need to mess with the linker flags to add support for ARM
toolchains other than CodeSourcery's. Since the toolchain is
determined in build-rules.mk, decisions that depend on it have to
happen after it's included.

These form and name of structs etc. is basically determined by the USB
spec and the libmaple style guide, so there's little reason for them
to change, and less reason for them to stay hidden.

Just change names and things to fit the libmaple style. Its contents
will move to the top-level <libmaple/usb.h> header next.
This API is still unstable, but we need to expose pieces of it in
order to get the Maple-specific pieces of usb_cdcacm.c into Wirish.
Adjust uses of the API appropriately.

We definitely need to mask out the high bits, as RM0008 doesn't
specify that they read as zero. Calling this function seems to crash
the board, though. I'm not sure why, especially since
usb_set_ep_tx_count(), used by usb_cdcacm.c, seems to work.
Confusing.

Mark internal state static. Properly reset the RX/TX state on USB
reset. Choose better names for countTx and newBytes.
Move the exposed configuration back into the .c; this information is
not beneficial to hooks.

Actually fill the TX buffer in the packet memory area, so we can send
more bytes per transaction. Using the test-session benchmark, we're
now clocking in the high 700KB/sec range via PySerial. With screen,
rate is now about 550 KB/sec.

I'm currently measuring over 500 KB/sec with screen as my serial

Rename USB_Line_Coding to usb_line_coding, and rename its fields to
match the spec to aid searches. Alter the line_coding global to match,
fixing an incorrect comment and avoiding magic numbers.

Use usb_cdcacm hooks to move the DTR edge and "1EAF" magic packet

We need this so the bootloader reset signal detector can look ahead in
the byte stream without stealing bytes from the user when "1EAF" isn't
received.
While we're doing this, take the time to fix a bunch of RX-related
code (dead code removal, adding volatile, etc.)

Mark the API as unstable so people don't rely on these too hard. (This
header is not part of the official libmaple docs). We'll need some of
this configuration elsewhere later, and it doesn't make much sense to
expose it piecemeal.

The disc pin code was copy-pasted when the CDC ACM pieces were
extracted from the rest of the USB code, and I didn't really
understand what was going on when I moved it over. Having checked the
spec, the comments can be safely improved.

Support the extended erase memory command, which replaced the erase
memory command in the bootloader protocol as of version 3.0. This
takes a long time, so tweak _wait_for_ask to take an extra timeout for
special cases like this.
Use this under if __name__ == '__main__' to support F2 and
F4. Additionally, produce a human-readable report of the target chip
from its chip ID.
