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.

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.

Sigh; Emacs's elide-head feature makes it easy to forget to update

probably use voidFuncPtr instead, but this way people can see that the function expects something different. Existing functions haven't changed in signature.

This reverts commit 715a63dccb3a39d7d0502fb39b900c8302a60a87. 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.

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.

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

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

Rip out the existing nonportable pieces, and shove them under
wirish/stm32f1, using weak symbols so users who only want libmaple
proper don't end up with build errors. Add stubbed-out (and only
partially functional) definitions for F2 targets under wirish/stm32f2.
The behavior on F103 targets is the same as it was before (though the
assertion framework has always been broken and badly needs
replacement, that awaits another commit). We additionally now skip
re-enabling USB on F1 targets without USB, to make things work on
value line MCUs.

We can implement it in terms of _i2c_bus_clk() instead of hard-coding
STM32_PCLK1.
This might be overkill, since I2C peripherals are slow and thus likely
to be on APB1 for all STM32 devices (that is the case for F2/F4, for
instance), but if we're going to have _i2c_bus_clk(), we might as well
respect it.

This won't work on F2, which at times has SDA and SCL on different
ports (e.g. I2C3 SDA on PC9, SCL on PA8). Add .sda_port and .scl_port
replacements, which are used when the now-deprecated .gpio_port is
null. Use them correctly everywhere, with some new i2c_private.h
helper functionality.
Sigh. The F1 I2C code tries too hard to guess what you wanted; it's
not porting well at all.
