encoding: Improving structure and documentation of block helpers
This commit add several new helpers to simplify operations with
std::string:
- prependStringBlock
- makeStringBlock
- readString
The following functions are deprecated and their replacements:
- nonNegativeIntegerBlock (use makeNonNegativeIntegerBlock)
- prependBooleanBlock (use prependEmptyBlock)
- booleanBlock (use makeEmptyBlock)
- dataBlock (use makeBinaryBlock)
- nestedBlock (use makeNestedBlock)
