CodeSnip Old Code (SVN)

Merged trunk changes r522-534 into the delphi2010-port branch.

* Added new IsValidDriveLetter function.
* Re-implemented ContainsWhiteSpace in a Unicode friendly way.

Delete redundant private IsWhiteSpace routine from UUtils unit. Version in UUnicodeHelper unit now used in preference.

* Changed character set testing code in several units to use char set helper functions added to UUnicodeHelper.pas instead of testing directly against literal or constant sets. This prevents Delphi 2010 warnings about WideChar being reduced to byte char in set expressions.
* Changed use of UpCase built-in to use ToUpperCase function added to UUnicodeHelper.pas.
* Added various set handling routines along with ToUpperCase function. These mainly call TCharacter methods on Unicode Delphis and have custom implementations on other Delphis.

Merged trunk changes r401:429 into the delphi2010-port branch.

Made minimal changes to get CodeSnip to compile with Delphi 2010. The resulting build has numerous warnings and does not work correctly. Most changes relate to Unicode compatibility, but some relate to other Delphi 2010 changes or changes to the Indy component library.

Development branch to make project compatible with Delphi 2010.
