* Move including menuScan.dbd from menuGlobal.dbd to base.dbd.
Menus included in menuGlobal.dbd can't be overridden at build
time since it gets fully expanded before installation.
* Convert .dbd.pod files before generating menuGlobal.dbd.d
* Remove menuCompress.dbd, nothing in Base uses it any more.
The compress record has its own compressALG menu
The auto-generated base.dbd file has all the includes fully
expaded out before installation, which prevents IOC applications
from being able to replace manuScan.dbd and menuconvert.dbd
Combine recIoc and softDevIoc libraries into dbRecStd
Move base.dbd from ioc/misc/ to std/softIoc/
Generate stdRecords.dbd from the std/rec/Makefile list of record
types instead of hard-coding it in base.dbd
