Solves a problem when building in strict C++ mode, as GCC defines
uint32_t as unsigned long on systems where sizeof(long) == 4. This
causes GCC to complain that uint32 != uint32_t as unsigned int !=
unsigned long.

This resolves issues related to sending full (64B) packets via USB
2.0. In this case, some hosts continue to expect more data. Add
infrastructure for sending 0-byte packets to signal end of
transmission, and use it in SerialUSB.

- Check if we're transmitting (instead of how many bytes are left
untransmitted) before bailing, in case we're transmitting a
zero-length packet.
- Set transmitting=1 before setting the endpoint valid to avoid races
with the USB interrupt.
- Eliminate some duplicated code.

Added a flag to see if we are currently waiting on an interrupt to acknowledge the sending of the current
IN packet.
Added a method usb_cdcacm_is_transmitting() to check for that flag.

I am not sure why this would work for most DMA transfers but I ran into trouble when doing
SDIO DMA.

It is possible to receive empty bulk transfers. This would lead to the endpoint never being reenabled as this was handled by the read routine. This caused the USB to hang.

stm32f1/performance: load stm32.h in order to have STM32_HIGH_DENSITY when necessary
STM32_HIGH_DENSITY was not defined in isrs.S and vector_table.S for a high density STM32. This was because stm32.h where the flag is now defined (in contrast to being defined on the command line in an earlier version of libmaple) was not included. This led to crashes when using one of the high density peripherals.
Updated the ASFLAGS to have the correct include path in rules.mk.
Include stm32.h in the assembler files.

This reverts commit 715a63dccb. It fails
to build using the 2010 CodeSourcery toolchain, which is still the latest
officially supported version.

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.

This was already supported, so just move the line coding structure to
the header and add some functions for accessing the current values.

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.

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.
Other minor fixups and comment improvements.

Use usb_cdcacm hooks to move the DTR edge and "1EAF" magic packet
detection to usb_serial.cpp. We'll later be able to extend this system
to support Leonardo-style reset signalling.
