Yukihiro "Matz" Matsumoto c46f9e0793 mruby-compiler: fix uninitialized memory in realloc_pool_str()

when converting a shared/static string (IREP_TT_SSTR) to heap-allocated
(IREP_TT_STR), copy the original content to the new buffer.

previously, the original content was lost when allocating new memory,
leaving the first bytes uninitialized. this caused find_pool_str() to
read uninitialized memory via memcmp() when searching for duplicate
strings.

reported by OSS-Fuzz.

mruby-compiler

This mrbgem provides the mruby compiler, which is responsible for parsing Ruby code and generating mruby bytecode.

Functionality

The mruby-compiler gem includes the following components:

Parser: Translates Ruby source code into an abstract syntax tree (AST).
Code Generator: Traverses the AST to produce executable mruby bytecode.
mrbc executable: A command-line tool for compiling .rb files into .mrb bytecode files.

Usage

The mrbc (mruby-bin-mrbc) executable will generate compiled binary from Ruby programs via this gem.

Example of using mrbc:

# Compile a Ruby script to bytecode
bin/mrbc my_script.rb

# Run the compiled script
bin/mruby my_script.mrb
