pancake e8af14966b * Import the r_regex api in libr/util/regex from OpenBSD source
- Added a r2-like API on top of it
  - Make RSearch and RMagic use this new api, so
* Only load default magicpath files when no file is passed to RMagic
* Initial work on r_listrange optimization in RAnal
  - #define USE_NEW_FCN_STORE
  - Still work-in-progress
* Implemented a RPoolFactory singleton api to accelerate
  allocations of little objects in the future
* Fix sys/mingw32.sh for osx
* Added sys/maemo.sh
