Remove debug leftovers that were causing memory corruption.
Writes of 64 or more bytes from the USB host side caused memory
corruption before this commit.
I've tested it in a STM32L4 board and it is working as expected.
115200 is a much more sane "default" than 38400.
Instead of a mix of 38400 and 115200, just use 115200 in all places.
There's no reason for modern 32bit cpus to be using such old slow
baudrates.
Tested on f1, f4, l1. Replaced some old f1 code that predated some
library support code for this.
Not strictly required as we're using port A out of the box, but makes
for bad example code, when the syscfg clock is required for selectin
exti sources other than port A.
Fixes: b8b97209 stm32l4: basic uart/exti/led/clock demo
which introduced the l4 example, but left out the makefile.include file
and didn't add it to the root build.

HSI is out of spec for reliable USB operation, even though it sometimes
works. stm32-h103 board has an 8Mhz external crystal which should
therefore be used for any USB work.

USB_VBUS is not an alternate function, it is an additionnal function which is
always enabled.
If configured as an alternate function, it will draw current from VBUS.
gdb will actually accept as little "tar ext :4242" but use the full
commands to help clarify the intent for people who might not be as
familiar with the syntax.
This adds a section to the bottom of the .map file containing the
symbol->object file mapping. (the logical inverse of the existing
section at the start of the .map file that lists objects, and the
symbols that pulled them in)

can fixes are compile tested only. I don't have those boards.
f3 i2c is tested on i2c and gives the same results
l1 low power demo seems to have been broken for some time already.
=> should be fixed, but not something I'm going to work on right now.
There was an attempt at providing support for the texane/stlink utility.
It has been broken for a long time, referring to missing scripts.
Remove it as clearly unused.
