Subject: race condition of managed gdd

Hi,

This was originally reported as a crash of PCASpy 0.6.2.
https://github.com/paulscherrerinstitute/pcaspy/issues/25

The managed gdds are in a linked list, in class gddApplicationTypeTable. The race condition happens between getDD and freed operations when accessing this list.

Here is the proposed patch,
https://github.com/xiaoqiangwang/epics-base/commit/a2132a1f79ce8f026743db4704fc0e9528828bf8

Best
Xiaoqiang
