e1fed5439c 53782: Src/params.c, Test/K01nameref.ztst: changes to nameref base level: 
- avoid changing base on assignment;
 - omit base level for up-scope references
 - do not follow reference chains for base level of new references

abd541e18c 53568: fix additional problems with reference scoping, update documentation 
Scope exits could miss some scope updates in named reference chains.
References declared -u behave like any other reference upon scope exit.

f555e902db 53546,53557 (plus test): Fix scoping of "placeholder" named references 
When using placeholders declared several levels earlier than assignment:
1) Searching "up" for "typeset -n -u" could find deeper locals than intended
2) Searching for a subscript reference could skip to the top level
3) Exiting a function scope could incorrectly change the reference level

6bb792dba8 53257: use monotonic clock where appropriate 
update the following features to use the monotonic clock for calculating time
deltas and intervals:

* MAILCHECK parameter
* PERIOD parameter
* SECONDS parameter
* %(nS.t.f) prompt-expansion sequence
* time built-in's elapsed time and cpu % values
* zsh/zftp ZFTP_TMOUT parameter
* zsh/zprof timings

also use CLOCK_MONOTONIC_RAW instead of CLOCK_MONOTONIC on macOS

baa19d2a85 51945: assorted documentation improvements, bug fixes, and new test 
1) Document the behavior of "typeset -n existing_var" (via Jun T. comment)

5) Allow "typeset +r -n ref" and "typeset +r +n ref" (Jun T.)
6) Fix "typeset -r -n ref=param" to create readonly references
7) Avoid accidental removal of PM_UNSET flag (Jun T.) and update test
8) Fix "typeset -gn ref=value" and add a test for it
9) Add tests for read-only reference behavior
10) Fix infinite recursion when resolving scope of an unset local
named reference, add test.

32cceefa95 51437: Fix incorrectly-passed test case, masked by unrelated bug. 
A bug with zmodload when unloading/reloading a static module caused the
state of the shell options to change during K01 test.  Worked around it.
Also changed warnnestedvar messages to look more like other such.

3eed6f70cd 51402: Some ksh/bash features, additional sanity checking 
* Add "unset -n"
* Allow and enforce "typeset -n -r" for read-only references
* "can't change type via subscript reference" error
* Better checking for self-referential declarations/assignments
* Ksh-style "foo=bar; typeset -n foo" creates foo=bar reference
* Support "typeset -n ref; for ref in ..."
* Subscripted references use NO_EXEC for safety
* References assigned in called scopes reset scope at end
* Allow named references to $! $? $$ $- $0 $_
