* ^#t("a","#TRHASH",71945627,1)="a"_$C(0)_"1"
*
* Key aspects of the format change
* ----------------------------------
* 1) New ^#t("#LABEL")="3" to indicate the format of the ^#t global. This is in addition to
* ^#t("a","#LABEL") etc. which is already there. This way we have a #LABEL for not just the installed
* triggers but also for the name information stored in the #TNAME nodes.
* 2) In the BHASH and LHASH fields. The hash computation is different so there are more chances of BHASH and LHASH
* matching in which case we store only one #TRHASH entry (instead of two). So thre is fewer ^#t records in the new
* format in most cases.
* 3) ^#t("a","#LABEL") bumps from 2 to 3. Similarly ^#t("a","#CYCLE") bumps by one (to make sure triggers for this
* global get re-read if and when we implement an -ONLINE upgrade).
* 4) DEFAULT used to have ^#t("#TNAME",...) nodes corresponding to triggers across ALL regions in the gbldir and
* other regions used to have NO ^#t("#TNAME",...) nodes whereas after the upgrade every region have
* ^#t("#TNAME",...) nodes corresponding to triggers installed in that region. So it is safer to kill ^#t("#TNAME")
* nodes and add them as needed.
* 5) #TRHASH has moved from ^#t() to ^#t(<gbl>). So it is safer to kill ^#t("#TRHASH") nodes and add them as needed.
*
* Below is a sample layout of the label 4 ^#t global
* -------------------------------------------------------
* ^#t("#TNAME","x")="a"_$C(0)_"1" (present in CURRENT region)
* ^#t("a",1,"BHASH")="71945627"

* ^#t("a","#CYCLE")="2"
* ^#t("a","#LABEL")="4"
* ^#t("a","#TRHASH",71945627,1)="a"_$C(0)_"1"
*
* Key aspects of the format change
* ----------------------------------
* 1) Removed ^#t("#LABEL") as it is redundant information and trigger load does not include it
* 2) Multiline triggers were incorrectly processed resulting in incorrect BHASH and LHASH values. Upgrade fixes this
* 3) ^#t("a","#LABEL") bumps from 3 to 4. Similarly ^#t("a","#CYCLE") bumps by one (to make sure
* triggers for this global get re-read if and when we implement an -ONLINE upgrade).
