since Java on my machine throw stack overflow exception around 3900.

e6892996b1 ICU-22584 Fix RBBI rule builder stack overflow. 
The problem was found by fuzz testing.

A rule consisting of a long literal string produces a large, unbalanced parse tree,
one node per string element. Deleting the tree was recursive, once per node, resulting
in deep recursion.

This PR changes node deletion to use an iterative (non-recursive) approach.

This change only affects rule building. There is no change to the RBBI run time
using pre-built rules.

866254ef12 ICU-21180 BreakIterator, change all NULL to nulptr 
In the C++ break iterator code, change all use of NULL to nullptr.
This is in preparation for follow-on PRs to improve out-of-memory error handling
in Break Iterators, keeping use of nullptr consistent between old and new
or updated code.

030fa1a479 ICU-21148 Consistently use standard lowercase true/false everywhere. 
This is the normal standard way in C, C++ as well as Java and there's no
longer any reason for ICU to be different. The various internal macros
providing custom boolean constants can all be deleted and code as well
as documentation can be updated to use lowercase true/false everywhere.

0ec329c6e1 ICU-21662 Improve UVector error handling. 
This is the next installment of UVector error handling cleanup. It includes:

- Revise UStack to follow the conventions of UVector, to leave the stack
  unmodified when there is an incoming error code. And, for stacks with a
  deleter function, to delete the incoming object if it cannot be
  succesfully pushed.

 - Review all useage of UStack in ICU; adjust call sites as needed.

 - Review all uses of UVector::addElementX() in the implementation of
   - Regular Expressions
   - Break Iteration
   - toolutil/xmlparser

   changing to the updated functions, and adjusting call sites as needed.

c26aebe802 ICU-21662 Rename UVector::addElement(). 
This is the first step towards improving the error handling and out-of-memory
behavior of UVector::addElement(). A followup PR will add back a new addElement()
with corrected error handling, then additional followups will switch call sites
from the original (renamed) function to the new addElement().

This commit includes no logic or behavior changes; it only renames the existing functions.
