Replaces the special heap command approach of the lpc_common module with a more general heap command approach. Module lpc_common was already removed with PR #2118. PR #2118 integrated cpu/lpc_common code in cpu/lpc2387. With PR #3530 special heap handling for cpu/lpc2387 was replaced by newlib memory management which uses _sbrk_r to allocate chunks from the heap. _sbrk_r uses _sheap and _eheap symbols that are defined in lpc2387.ld and can be used together with mallinfo function for heap statistics.
UART FIFO must contain only 1 byte when newlib's `printf` function is used. Otherwise, outputs that are still not sent over UART are lost when `printf` is called asynchronousely.
To avoid unresolved symbols for unused functions during linking, compiler option `-ffunction-sections` is used now. Linker option `--warn-unresolved-symbols` is removed to get errors if required symbols cannot be resolved.
The modules `newlib, `newlib_syscalls_default` and `stdio_uart` are now used by default for output to the UART interface. This also reduces the dependency rules.
The overridden stdio functions `puts`, `putchar` and `printf` were removed. Instead, the corresponding newlib functions are always used. Using the newlib functions fixes output conflicts when using `f *` functions like `fprintf`,` fputs`, ... with `stdout` as the file parameter.
This is to avoid conflics with other config.h files, e.g. when building
for esp8266 where $(NEWLIB)/xtensa-lx106-elf/include/config.h gets
included instead.
The test randomly fails on `native` due to timers being not accurate but
it cannot be otherwise. So better disable it than raising fake errors.

- Nucleo-f091rc can become unflashable when hardfaults occure.
To make sure flashing succeeds `connect_assert_srst` is called
before connecting to flash threw openocd.
- Add a variable to add extra openocd commands before resetting
a board. These will not be called when `debug`, in contrast
to OPENOCD_CONFIG, OPENOCD_EXTRA_INIT and OPENOCD_ADAPTER_INIT.
- Add connect_assert_srst to reset config if
OPENOCD_RESET_USE_CONNECT_ASSERT_SRST=1
