Add support for dynamic buffer sequences.

This commit adds:

- New dynamic_string_buffer and dynamic_vector_buffer adapter classes that meet
  the DynamicBufferSequence type requirements.

- New dynamic_buffer() factory functions for creating a dynamic buffer adapter
  for a vector or string.

- New overloads for the read(), async_read(), write() and async_write(),
  read_until() and async_read_until() free functions.

N.B. the read_at, async_read_at, write_at and async_write_at functions have not
yet been updated to support dynamic buffer sequences.
