545: Add adapter for implementing async traits for blocking types r=lulf a=lulf
This allows writing drivers relying on async traits, while still
functioning with implementations that already implement the embedded-hal
traits.

563: Initial ADC support for on STM32F1xx r=Dirbaio a=sjoerdsimons
Add an ADC implementation for F1 based chips. Primarily tested using ADC1, proper functionality for ADC2 probably needs some extra work as it's mainly a slave and can't e.g. measure vrefint by itself.

558: Port buffered uart to v1 stm32 hardware r=Dirbaio a=DCNick3
#526 seems to suggest that it will be rewritten for DMA support, but I am not sure how to implement it and the port was quite straightforward, so here it is. It might be immediately useful before DMA version will be implemented
Note that I have not tested this on v2 hardware

Previously disable_channel enabled rather than disabled the requested
channel due to an apparent copy-paste error. Refactor to eliminate this
sort of issue by construction.
This allows writing drivers relying on async traits, while still
functioning with implementations that already implement the embedded-hal
traits.
Add examples to stm32l4 for using this feature.
`async fn`s do nothing until polled, but we want the DMA transfer to
immediately start in this case. Drivers rely on it. Some require special
orders, such as "start DMA, start SPI, then wait for DMA" which is awkward
to do without eager start.
Also use a manually-impl'd future, this allows getting rid of the "double"
Unborrow channel clone.
