`prependDataBufferIfValid` overloads

== Synopses

Declared in `<bdlbb_blobutil.h>`

Insert the specified move‐insertable `buffer` before the beginning of the specified `dest` if neither the resulting total size of `dest` nor its resulting total number of buffers exceeds `INT_MAX`. Return 0 on success, and a non‐zero value (with no effect) otherwise. The length of the `dest` is incremented by the length of the prepended buffer. In case of success the `buffer` is left in a valid but unspecified state.
