`copy` overloads

== Synopses

Declared in `<bdlbb_blobutil.h>`

Copy into the specified `dst` starting at the specified `dstOffset` the specified `length` bytes from the specified `src`. The behavior is undefined unless `0 <= dstOffset`, `0 <= length`, `dst || 0 == length`, `src || 0 == length`, `!dst || dstOffset <= dst‐>length() ‐ length`, and `src` refers to a buffer with at least `length` bytes. Note that this operation does not require `dst` to have a blob buffer factory in that it does not create or destroy blobs ‐‐ it simply copies data from `src` into `dst`, so `dst` must already have room for `length` bytes of data added at `dstOffset`.

Copy the specified `length` bytes starting at the specified `position` in the specified `srcBlob` to the specified `dstBuffer`. The behavior of this function is undefined unless `0 <= length`, `0 <= position`, `position <= srcBlob.totalSize() ‐ length`, and `dstBuffer` has room for `length` bytes. Note that this function does _not_ set `dstBuffer[length]` to 0.
