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.

ROM method tables used static mrb_mt_tbl variables shared
across the process. The next pointer in each wrapper was
mutated by mrb_mt_init_rom(), causing cross-state
contamination when multiple mrb_state instances existed.
Allocate mrb_mt_tbl wrappers per-state via mrb_malloc().
The const mrb_mt_entry[] arrays remain static and shared.
Wrappers are tracked in mrb->rom_mt and freed at mrb_close().
Remove MRB_MT_ROM_TAB macro; add MRB_MT_INIT_ROM macro that
auto-computes size and calls the new mrb_mt_init_rom().

Move MRB_METHOD_FUNC_FL to bit 24 and visibility flags to
bits 25-26 so that MRB_ARGS_*() values (bits 0-23) can be
stored directly without shifting. This makes MRB_MT_PRIVATE
and MRB_METHOD_PRIVATE_FL the same value, eliminating the
dual-constant confusion and simplifying the MRB_MT_ENTRY()
macro to a single OR operation.

Restore MRB_ARGS_* argument specs and ISO section comments to all
709 ROM method table entries. The aspec is encoded in bits 4-27 of
the flags field; MRB_MT_NOARG is now auto-derived from aspec==0.
Add MRB_MT_ENTRY_PRIVATE() macro for private methods (53 entries)
and MRB_MT_ASPEC() accessor for extracting aspec from flags.

Since ROM table entries are always C functions, have the
MRB_MT_ENTRY() macro set MRB_MT_FUNC automatically. This
simplifies entry definitions across all 32 source files.

Replace binary search with linear scan in mt_get(), mt_put(),
mt_del(), mt_chain_has(), and mrb_mt_foreach(). The method cache
makes repeated lookups O(1), so linear scan on cache misses is
acceptable.
This removes the sorting requirement, allowing ROM entry arrays
to be declared const. On embedded systems, const static data
resides in flash/ROM instead of RAM, saving ~8.4KB for ~700
method entries on 32-bit MCUs.

Replace the parallel-arrays (struct-of-arrays) ROM method table
layout with an array-of-structs layout where each mrb_mt_entry
bundles its function pointer and symbol key together.
New MRB_MT_ENTRY() and MRB_MT_ROM_TAB() macros simplify ROM table
definitions from a 3-part pattern (SIZE define + anonymous struct +
mrb_mt_tbl) to a 2-part pattern (entries array + mrb_mt_tbl).
Internal mt_* functions in class.c are simplified: single memmove/
memcpy operations replace paired key+value operations.

Remove the unused mrb_state parameter from KHASH_FOREACH macro to clean
up the API. The parameter was never used in the macro implementation and
only cluttered the call sites.
Changes:
- Update KHASH_FOREACH macro signature: (name, mrb, kh, k) -> (name, kh, k)
- Update documentation and usage examples in khash.h
- Update KSET_FOREACH wrapper macro in mruby-set
- Update 2 direct call sites in mruby-metaprog
- All mruby-set call sites automatically updated via wrapper macro
This is a breaking change but follows the recent API cleanup where we
already modified KHASH_FOREACH signature. The macro now has a cleaner
interface without the unused parameter.

Replace XML-style markup tags in comments with markdown equivalents:
- <code>...</code> to `...` (inline code)
- <tt>...</tt> to `...` (teletype/monospace)
- <i>...</i> to *...* (italics/emphasis)
- +...+ to `...` (parameter/variable references)
Updated 80+ files across core source, headers, mrbgems, and libraries
to use consistent markdown formatting in documentation comments.
Handled edge cases including special characters like <=> operators.

When calling `mrb_equal()` or `mrb_funcall()` family functions, the GC arena should be restored if the loop is repeated by a non-immediate return value.
In my opinion, restoring the GC arena is unnecessary when a non-immediate (true) value causes the function to return (e.g. the `mrb_ary_index_m()` function).
The patch does not take into account the case of recursive calls and may be incomplete.
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`.
- Added to `mruby-binding-core`
- `Binding#local_variable_defined?`
- `Binding#local_variable_get`
- `Binding#local_variable_set`
- `Binding#local_variables`
- `Binding#receiver`
- `Binding#source_location`
- `Binding#inspect`
- Added to `mruby-proc-binding`
- `Proc#binding`
The reason for separating `Proc#binding` is that core-mrbgems has a method that returns a closure object to minimize possible problems with being able to manipulate internal variables.
By separating it as different mrbgem, each user can judge this problem and incorporate it arbitrarily.
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.
Integrate the implementation with `Module#define_method`.
- Introduce the internal function `mrb_mod_define_method_m()` (no static)
- The `Object#define_singleton_method` method can now accept a second argument
The "a"/"*" specifier of the `mrb_get_args()` function will now return `const mrb_value *`.
This is because it is difficult for the caller to check if it is an array object and write-barrier if necessary.
And it requires calling `mrb_ary_modify()` on the unmodified array object, which is also difficult (this is similar to #5087).
They are basically the copy of instance variable tables. On my Linux
box, memory consumption of `mrbtest` measured by `valgrind` is:
- old: 17,683,830 bytes
- new: 14,283,749 bytes
