Tidied iocli exports, build macro tweaks. Removed 4 overloads of CCommandBase::RunCommand[L] that are no longer used at all, and changed one more to not be exported as it's only used internally to iocli.dll. fixed builds on platforms that don't support btrace or any form of tracing.

==name echo

==short-description

Print a text string to C<stdout>. If no text is specified as an argument, reads from C<stdin> and writes the result to C<stdout>.

==long-description

Note, this command used to interpret escape sequences such as C<^r> and C<^t> itself. This functionality has now been moved into C<CCommandBase> so all fshell commands can benefit from it. A consequence of this change is that it is no longer necessary to double escape such sequences.

==argument string string optional last

The text to be printed.

==option bool e stderr

Print to C<stderr> rather than C<stdout>.

==option bool w wrap

Wraps the text to the screen width, ensuring that words do not get split across lines.

==option uint i indent

The number of characters to indent the text by. Only has an effect when used with C<--wrap>.

==option enum a attributes multiple

The attributes to assign to the text written to the console.

==enum-value bold

==enum-value underscore

==enum-value blink

==enum-value inverse

==enum-value conceal

==option enum f foreground-color

The color the font glyphs are to be drawn in.

==enum-value black

==enum-value red

==enum-value green

==enum-value yellow

==enum-value blue

==enum-value magenta

==enum-value cyan

==enum-value white

==option enum b background-color

The color the rectangle behind the font glyphs is to be drawn in.

==enum-value black

==enum-value red

==enum-value green

==enum-value yellow

==enum-value blue

==enum-value magenta

==enum-value cyan

==enum-value white

==option bool B binary

Write to the console in I<binary mode>. Note, not all consoles support the notion of I<binary mode>. If not, KErrNotSupported (-5) will be returned. In practice, currently only the VT100 console variants support this.

==option bool n no-newline

By default echo will append a new line (C<CRLF>) on to the end of the C<string> argument, if it doesn't already have one. Use C<--no-newline> to prevent this.
