Support backtrace after method calls
...
GitHub: fix #2902 , #2917
The current implementation traverses stack to retrieve backtrace. But
stack will be changed when some operations are occurred. It means that
backtrace may be broken after some operations.
This change (1) saves the minimum information to retrieve backtrace when
exception is raised and (2) restores backtrace from the minimum
information when backtrace is needed. It reduces overhead for creating
backtrace Ruby objects.
The space for the minimum information is reused by multiple
exceptions. So memory allocation isn't occurred for each exception.

always define SIZE_ERROR_MUL() macro
...
Previously there wasn't a way to trigger the useful definition, but it
is needed and that in every case to check for integer overflow due to
multiplication and faulty/modified binary files.
Also change existing code to a calloc()-like parameter order.

remove SIZE_ERROR() macro
...
It's only used once and in that case it isn't necessary anyway, since
size_t must be at least 32 bits wide and
the max. length of a filename is UINT16_MAX.

fix possible unsigned integer underflow
...
buf_size has to be greater than header_size, otherwise subtracting
header_size from buf_size will cause an integer underflow.
Being equal to header_size is fine, however useless, so quit early.

allow endian specification of mrb files by mrbc -e/-E
...
`mruby -b` now accepts both big/little endian mrb (compiled binary) files.
`mrbc` generates mrb files in big endian for .mrb files and in native endian
for C files (with -B option specified) by default. If you are cross compiling,
you need to specify target endian by -e/-E options if it is different from
host endian.
