Apple needs CONFIG_RUNMEM_RO=1
I now only set CONFIG_RUNMEM_RO=0 on _WIN32
Openbsd does not have malloc.h so remove some code
Also fix some warnings when compiling lib with gcc
- LIBTCCAPI int tcc_set_backtrace_func(void *ud, ...)
accept opaque user data pointer,
- tcc -vv -run... : show section info
- use memalign() to allocate runtime memory
- printline_/dwarf : pass output to parent function
- tccpe.c : fix -nostdlib -run
- --config-backtrace=no : make it work again
- new LIBTCC API tcc_setjmp() to allow longjmps & signals
from compiled code back to libtcc per TCCState
- new LIBTCC API tcc_set_backtrace_func() to handle backtrace output
- move c/dtor/atexit stuff to runtime (lib/runmain.c)
- move bt-log.o into libtcc1.a
- add timeouts to github action (beware, it did happen to hang
infinitely in the signal handler at some point)
