Description

As a part of IGNITE-1816 I had to revisit our flags. Here are how they look now:

/** Flag: user type. */
public static final short FLAG_USR_TYP = 0x0001;

/** Flag: schema exists. */
public static final short FLAG_HAS_SCHEMA = 0x0002;

/** Flag indicating that object has raw data. */
public static final short FLAG_HAS_RAW = 0x0004;

/** Flag: offsets take 1 byte. */
public static final short FLAG_OFFSET_ONE_BYTE = 0x0008;

/** Flag: offsets take 2 bytes. */
public static final short FLAG_OFFSET_TWO_BYTES = 0x0010;

/** Flag: compact footer, no field IDs. */
public static final short FLAG_COMPACT_FOOTER = 0x0020;

The following changes must be made to CPP:
1) When schema exists (i.e. at least on non-raw fieid was written), HAS_ SCHEMA flag is set to true. This is the inversed version of what previously was "RAW_ONLY".
2) When raw data exists, HAS_RAW flag is set to true. This flag should be used to determine location of raw data.
DO NOT USE % for this anymore!
3) For now COMPACT_FOOTER should always be 0. If you receive an object with this flag set to 1, an exception must be thrown.
