[RFA 12/42] Move within_function to stabsread

- Subject: [RFA 12/42] Move within_function to stabsread
- References: <20180523045851.11660-1-tom@tromey.com>
The global within_function is only used by a few symbol readers. This
patch moves the global out of buildsym and into stabsread, which
seemed like a better fit. It also arranges for the existing readers
to clear the global at the appropriate time.
