Fix array size orders.

Note that the following code in HIDL:
    typedef int32_t[3] ThreeInts;
    struct T {
        ThreeInts[5]  matrix5x3;
        int32_t[3][5] matrix3x5;
    }

will generate this C++ code:
    struct T {
        hidl_array<int32_t, 5, 3> matrix5x3; // notice 3 is after 5
        hidl_array<int32_t, 3, 5> matrix3x5;
    }
and this Java code:
    public final static class T {
        public final int[][] matrix5x3 = new int[5][3];
        public final int[][] matrix3x5 = new int[3][5];
    }

hidl-gen user guide

1. Build

croot
make hidl-gen

2. Run

hidl-gen -o output-path -L language (-r interface-root) fqname

output-path: directory to store the output files.
language: output file for given language. e.g.c++, vts..

fqname: fully qualified name of the input files.
For singe file input, follow the format: package@version::fileName
For directory input, follow the format: package@version

interface-root(optional): prefix and root path for fqname.
If not set, use the default prefix: android.hardware and default root path
defined in $TOP.

examples:

hidl-gen -o output -L c++ android.hardware.nfc@1.0::INfc.hal
hidl-gen -o output -L vts android.hardware.nfc@1.0
hidl-gen -o test -L c++ -r android.hardware:/home/android/master/hardware/interfaces android.hardware.nfc@1.0
