ioc: overhaul Group::show().  shows triggers

ioc: MappingType

ioc: pvxsgl -> pvxgl

ioc: separate group config singleton from server singleton

ioc: remove unnecessary forward declarations

ioc: qsrv runtime disable by default

ioc: compat w/ older Base

ioc: link pvxsIoc w/ DB libs

ioc: Channel proper detection of invalid PV

ioc: no need to keep vector<dbCommon*> around

ioc: fix initial group update for mappings w/o dbChannel

ioc: redo testing

split out group tests, only run with Base >= 7.0

ioc: minor

ioc: loc_bad_alloc

ioc: avoid symbol/DTYP clash with pva2pva

ioc: test record alias in group json

ioc: test put failure when SPC_NOMOD and DISP=1

ioc: test channel filters

ioc: unnecessary capture

ioc: avoid sharing Value between multiple subscriptions

It is possible to create two subscriptions through the same channel.

ioc: group subscription include queueSize

ioc: eliminate unused atomicMonitor

ioc: consolidate GroupSource::get()

avoid some indirection

ioc: pvRequest override of atomicPutGet

ioc: fix group non-atomic put

ioc: test asTrap hooks

ioc: test putOrder also sets field order

ioc: simplify GroupConfigProcessor::loadConfigFiles()

Also ensure that groupMapMutex is held

ioc: testqgroup cover JSON def.

ioc: dbLoadGroup() use macros

ioc: pvxsl() take integer argument

ioc: display.form and info(Q:form

ioc: "NO_ALARM" -> ""

ioc: use dbServer

at least for informational callbacks.

ioc: consolidate createRequestAndSubscriptionHandlers()

ioc: eliminate ChannelAndLock

properties dbChannel doesn't need a separate DBManyLock

ioc: test that putOrder also controls field order

ioc: MappingType -> MappingInfo

Handle info(Q:time:tag
Add +type:"const"
