`trim` overloads

== Synopses

Declared in `<bdlb_string.h>`

Remove all leading and trailing whitespace characters from the specified `string`. If `string` consists of only whitespace then it will be empty (i.e., have 0 length) after this operation. The behavior is undefined unless `string‐>size() <= INT_MAX` (if applicable). See `bdlb_stringviewutil` for an identically named method having similar semantics taking (and returning) `bsl::string_view`.

Remove all leading and trailing whitespace characters from the specified `string` having the specified `length`, and load into `length` the number of characters in the resulting (trimmed) string. If `string` consists of only whitespace then it will be empty (i.e., have 0 length) after this operation. The behavior is undefined unless `0 <= *length`. Note that `length` is both an input and output parameter. See `bdlb_stringviewutil` for an identically named method having similar semantics taking (and returning) `bsl::string_view`.
