mostly doc-related, i.e. use @name for groups instead of @brief ... though this was overseen when merging the original code.

@smlng Too late for the 2019.04 release but not too late for next release 😄 I would like to make some progress with this PR (as well as with #10929) since these PRs provide important improvements that are prerequisites for the reimplementation of ESP8266 port in PR #11108.

Sorry that I'm pushing a bit 😎 but the conflicts with current master in PR #11108 are already increasing a lot. It will become more and more difficult to resolve all these conflicts while guaranteeing that the reimplementation PR #11108 keeps as stable as it already was. It was already tested completely.

Side note: careful with my GitHub name, its smlng with lower case L not i, i.e. no vowels. The other guy (sming) already got annoyed a couple times 😬

Ups 😎 Usually, I only type in 'sm' and use the completion which is usually 'smlng'. I didn't take much care. I thought Github is intelligent enough to know from the context of the PR that I didn't want to refer 'sming'.

cpu/esp8266: add LoadStoreError exception handler
de91b8d 
Usually, the access to the IROM (flash) memory requires 32-bit word aligned reads. Attempts to access data in the IROM (flash) memory less than 32 bits in size triggers a LoadStoreError exception. With the exception handler from esp-open-rtos it becomes possible to access data in IROM (flash) with a size of less than 32 bits and thus to place .rodata sections in the IROM (flash).

@smlng Thanks again for your fast support.

Sure thing. I now have a couple of ESP lying around at work and home, so I'm happy to help where ever I can to keep the RIOT support for ESP up and running (and improving)!
