Since presym is now mandatory, mruby.h includes presym.h so that
MRB_SYM() macros are available everywhere without explicit include.
Remove redundant #include <mruby/presym.h> from all source files.

Extract find_command_by_word1() and find_command_by_words()
from parse_command(), separating command-table lookup from
tokenization logic.

Both dbgcmd_run() and dbgcmd_quit() defined an exception class
and raised it with identical code. Add a shared static inline
helper in mrdb.h.

The three commands shared identical dispatch logic. Extract a
shared dbgcmd_set_breakpoint() that takes function pointers,
reducing each command to a one-line wrapper.

Extract common breakpoint slot allocation logic from
mrb_debug_set_break_line() and mrb_debug_set_break_method()
into a shared alloc_breakpoint() helper.

since all current uses check for failure (!MRB_OPEN_SUCCESS), add
MRB_OPEN_FAILURE() as the primary macro for better readability. define
MRB_OPEN_SUCCESS() in terms of MRB_OPEN_FAILURE() to avoid duplication
and optimize the common case. update all usage sites to use the clearer
MRB_OPEN_FAILURE() form.

made mrb_print_error() handle NULL by printing "Failed to allocate
mrb_state" when mrb is NULL. since mrb_close() already handles NULL,
this allows simplified error checking pattern:
if (!MRB_OPEN_SUCCESS(mrb)) {
mrb_print_error(mrb); // handles NULL
mrb_close(mrb); // handles NULL
return EXIT_FAILURE;
}
updated all binary tools (mruby, mirb, mrdb, mrbtest) to use this
simplified pattern, removing nested if checks.

changed mrb_open() and mrb_open_core() to return mrb_state with mrb->exc
set (instead of NULL) when initialization fails. this allows callers to
programmatically inspect error details, which is essential for embedded
systems without stderr. return NULL only for true allocation failure.
added MRB_OPEN_SUCCESS(mrb) macro to check initialization success, since
mrb != NULL no longer guarantees success. updated all binary tools
(mruby, mirb, mrdb, mrbtest) to use new pattern: check MRB_OPEN_SUCCESS,
print exception details via mrb_print_error if available, then mrb_close.
mrb_core_init_protect now preserves exception in mrb->exc instead of
printing and clearing it, giving caller control over error handling.
breaking change: callers must use MRB_OPEN_SUCCESS(mrb) or check both
mrb != NULL && mrb->exc == NULL. old NULL-only checks will miss
initialization failures.

Internal functions can only be called from within the library.
Functions listed in `mruby/internal.h` can be called from:
* core (src/*.c)
* gems (mrbgems/**/*.c)
But not from the application linked with `libmruby`.
Instead of including `mruby/presym.h` everywhere, we provided the
fallback `mruby/presym.inc` under `include/mruby` directory, and specify
`-I<build-dir>/include` before `-I<top-dir>/include` in `presym.rake`.
So even when someone drops `-I<build-dir>/include` in compiler options,
it just compiles without failure.
In addition, update the documents referring `build_config.rb` which is
no longer used. The new `build_config.rb` describes the new configuration
structure in the comment.
- `mrb_check_intern()` to return `mrb_value`
- `mrb_intern_check()` to return `mrb_sym` [NEW]
Other new functions:
- `mrb_intern_check_cstr()`
- `mrb_intern_check_str()`
They used to return `mrb_value` but now return `mrb_sym` for consistency
with other `intern` functions. If symbols are not defined, `check`
functions return `0`, instead of `nil` in the past.
It causes API incompatibility but I believe few people use those
functions out of the core, and those changes are very easy to handle,
hopefully.
