99dadf2998 compiler: allow comparative operators to have result other than Boolean. Reasons: 
1. It allows to use comparative operators in some unusual cases (issue #25004).
2. Regular type checking does not allow to use other than Boolean types in IF expressions anyway.
3. Delphi compatibility (although Delphi documentation states otherwise).

4d4ad5734b * Crt.CursorOn and CursorBig: use CX values that are CGA compatible, which makes them CGA/EGA/VGA compatible, because EGA/VGA bioses emulate CGA cursor values; as a side effect this also makes these functions work properly under EGA/VGA's 43- and 50-line text modes

08543ddeba Fix for Mantis #23899 . Allow to overwrite TStringList.ExchangeItems if necessary. 
rtl/objpas/classes/classesh.inc, TStringList:
  * rename the private ExchangeItems to ExchangeItemsInt and allow inlining
  + add a protected virtual ExchangeItems
rtl/objpas/classes/stringl.inc, TStringList:
  * Exchange: call ExchangeItemsInt
  + let default implementation of ExchangeItems simply call ExchangeItemsInt
  * QuickSort: call ExchangeItemsInt directly if there is no override otherwise call ExchangeItems

+ added test

b99cf8d680 * RTL: Changed 'shift' parameter of 64-bit shift helpers to CPU-native size, it doesn't have to be 64-bit because only its lower 6 bits are used. Not using 64 bit parameter improves code quality a bit.

6f5a648516 Improve the cpu type handling for M68k just in case we should branch 2.8.0 before I can start working on M68k again. 
Therefor the cpu type (-Cp...) "coldfire" was split up into "isaa", "isaa+", "isab" and "isac". The Linux RTL can currently compiled for "68020", "isab" and "isac". For the other three Bcc.L must be handled differently (only Bcc.B/W supported) and for "68000" also EXT.L needs to be handled differently.

fpcdefs.inc:
  + define CPUCAPABILITIES if capabilities can be set for a certain CPU type (currently ARM, AVR and M68k)
options.pas:
  * check for CPUCAPABILITIES instead of specific CPUs
assemble.pas:
  - the handling of the CPU type is already done in m68k/ag68kgas.pas, Tm68kGNUAssembler.MakeCmdLine (and thereby already using the gascputypestr array!)
m68k/cpuinfo.pas:
  - tcputype: remove "cpu_coldfire"
  + tcputype: add "cpu_isa_a", "cpu_isa_a_p", "cpu_isa_b" and "cpu_isa_c"
  + add "cpu_coldfire" constant which contains all Coldfire specific cpu types
  * adjust "cputypestr" and  "gascputypestr"
  + add tcpuflags and cpu_capabilities (DBRA restriction was checked with CPUCOLDFIRE, CAS/TAS will be needed for atomic operations and BRAL restriction was discovered during testing of new cpu types)
m68k/cgcpu.pas:
  * adjust checks for "cpu_coldfire"
m68k/n68kadd.pas:
  * don't use a BRA.L if it is not supported, but (at least for now) a BRA.W
aggas.pas:
  * adjusted check for Coldfire
