Summary of changes

Fixes #15498

Adds 2 boolean flags to the STM32 i2c_s object, to indicate whether a transfer is in progress, separate from the existing "transfer pending" flags.

i2c_slave_write, i2c_slave_read and their associated callbacks are modified to use these flags in addition to the pending flags.
The original behavior of the pending flags is preserved.

Nice catch on this, and this seems like a good fix! We'd love to have this PR over at mbed-ce/mbed-os!

By the way, as to regression tests, I actually have some ideas about that. I've been putting together a PCB which can test lots of different communications busses, and I also put together an I2C master test suite (which is what let me rewrite and fix all the STM32 I2C master mode code a year or two ago). Haven't really worked on slave mode yet I'm afraid...

Do you want like a 1 paragraph summary, or the entire post?

EDIT: oops I thought this notification was for my other PR

Fixes ARMmbed#15498

Adds 2 boolean flags to the STM32 `i2c_s` object
to indicate whether a transfer is in progress,
separate from the existing "transfer pending" flags.

`i2c_slave_write`, `i2c_slave_read` and their associated callbacks
are modified to use these flags in addition to the pending flags.
The original behavior of the pending flags is preserved.
