Fix: libsquashfs: add sqfs_free() function
On systems like Windows, the dynamic library and applications can easily end up being linked against different runtime libraries, so applications cannot be expected to be able to free() any malloc'd pointer that the library returns. This commit adds an sqfs_free function so the application can pass pointers back to the library to call the correct free() implementation.
