THRIFT-4269: Don't append '.' to Erlang namespace if it ends in '_'.
THRIFT-3834 added support for namespaces to the Erlang code generator.
However, that support uses a `.` between the namespace name and the type name.
This is inconvenient because, although `.` is a valid character in an Erlang
atom, atoms that contain `.` must be quoted. This means that a struct named
MyStruct in the namespace NS will generate a record named `'NS.MyStruct'`. The
rules for naming atoms in Erlang are:
> Atoms begin with a lower-case letter, and may contain alphanumeric
characters, underscores (_) or at-signs (@). Alternatively atoms can be
specified by enclosing them in single quotes ('), necessary when they start
with an uppercase character or contain characters other than underscores and
at-signs.
This pull request changes the Erlang code generator so that if an Erlang
namespace ends in a `_` then no `.` is added between the namespace and the
struct name when creating the record. This preserves the current behavior
unless the namespace ends is a `_`, but allow users to override the normal
behavior by adding an explicit `_` to the end of their namespace declarations.
