`appendDataBuffer` overloads

== Synopses

Declared in `<bdlbb_blob.h>`

Append the specified move‐insertable `buffer` after the last _data_ buffer of this blob; the last data buffer is trimmed, if necessary. The `buffer` is left in a valid but unspecified state. The length of this blob is incremented by the size of `buffer`. The behavior is undefined unless neither the total size of the resulting blob nor its total number of buffers exceeds `INT_MAX`. Note that this operation is equivalent to: ` const int n = blob.length(); blob.trimLastDataBuffer(); blob.insertBuffer(numDataBuffers(), MoveUtil::move(buffer)); blob.setLength(n + buffer.size()); ` but is more efficient.
