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.

081cf77330 ICU-21662 Improve UVector error handling. 
- Add updated versions of UVector::addElement() and ensureCapacity() that respect
  incoming errors.
  Follow on to c26aebe, which renamed the original versions.

- Add UVector::adoptElement() as a replacement for addElement() when the vector
  has a deleter function set, meaning that it adopts ownership of its elements.

  The intent is to make the behavior clearer at the call sites when looking
  at unfamiliar code.

- Make all functions with an incoming failure, as indicated by a UErrorCode parameter,
  leave the vector unchanged.

- Change all functions that store object pointers into the vector such that,
  when the store cannot be completed for any reason _and_ the vector has a deleter function,
  then the incoming object is deleted.

  This change can simplify the error handling code around calls to the affected functions
  (addElement() and insertElementAt(), in particular)

- Add index bounds checking on functions where it was possible - that is, on functions
  with both U_ErrorCode and index parameters.

- Changed to more modern C++ idioms in some parts of the UVector implementation.

- Review & update as required all uses of the UVector functions
  setElementAt(), insertElementAt(), setSize(), sortedInsert()
  these being the functions with changed behavior on error conditions
  (aside from addElement()).

This PR will be followed by more, switching call sites in various ICU services
from UVector::addElementX() (old behavior on errors)
to   UVector::addElement()  (new behavior on errors)

0a1cfa398c ICU-20973 Use standard keywords true & false to initialize type bool. 
Now when all equality operators return standard bool (commit 633438f),
it no longer makes any sense to use the ICU4C constants TRUE & FALSE
or local variables of type UBool for their return value.

98f9170004 ICU-20250 make UnicodeSet(intprop=value) faster 
- fastpath for UnicodeSet.add(new last range)
- fewer UnicodeSet memory allocations:
  initial internal list array, exponential array growth,
  allocate strings list/set only when first one is added
- faster CodePointTrie.getRange(): fewer calls to filter function
- revert UnicodeSet(intprop=value) from trie ranges to range starts + lookup
- cache per-int-prop range starts: fewer lookups

94fe10c710 ICU-11886 Speed up ucol_open by 21% 
* implement a deserialize constructor for UnicodeSet
 * add test cases for same
* add a generator (`gencolusb`) which can build `source/i18n/collunsafe.h`
* Note that for bootstrapping `collunsafe.h` can be truncated (zero length).
