Erhan Kurubas d3ffcc784d target/espressif: add algorithm support to execute code on target
This functionality can be useful for;
1-ESP flashing code to load flasher stub on target and
write/read/erase flash.
2-ESP GCOV command uses some of these functions to run
onboard routines to dump coverage info.

This is high level api for the Espressif xtensa and riscv targets

By definition in `target/target.h`, `coreid` is not a unique identifier
of a target -- it can be the same for targets on different TAPs.

Antonio Borneo 8670ad4caa target/espressif: fix clang report on list use
It looks like a false positive.
Scan-build considers as possible to:
- have list_empty() return false;
- list_for_each_safe() to not execute any loop, thus not assigning
  a non-NULL value to 'block';
- the NULL pointer 'block' is passed to list_del().
This is not possible because with list_empty(), the loop runs at
least once.

Rewrite the function to simplify the code and making it easier for
scan-build to check it.

This also drops an incorrect use of list_for_each_safe(), where
the 'safe' version was not required.
