Merged, thanks. Nit: "UnMount" should have been "Unmount" |

This prevents the archive handle from remaining unreleased after used, which could otherwise lead to memory overflows in certain situations. See also: 3ds-battery-patches#4
Additionally, the
MAKE_BRANCH_LINKmacro is now used to generate BL jump instructions tofsMountArchive,fsUnMountArchive, andfsRegisterArchive. This saves a few bytes in the LFS patch code, preventing issues where the replacement of thethrowFatalErrorfunction could exceed the original function size. The original LFS patch code used the BLX instruction, this is unnecessary because none of the three functions require switching to THUMB mode.Edit: This PR also fix #1954.
