Simon Tatham f39c51f9a7 Rename most of the platform source files.
This gets rid of all those annoying 'win', 'ux' and 'gtk' prefixes
which made filenames annoying to type and to tab-complete. Also, as
with my other recent renaming sprees, I've taken the opportunity to
expand and clarify some of the names so that they're not such cryptic
abbreviations.

* Function to obfuscate an input string into something usable as a

* the obfuscation depend on a key Windows stores for the owning user,

* length and be composed of filename-legal characters.
*
* Rationale: Windows's named pipes all live in the same namespace, so
* one user can see what pipes another user has open. This is an
* undesirable privacy leak: in particular, if we used unobfuscated
* names for the connection-sharing pipe names, it would permit one
* user to know what username@host another user is SSHing to.
*
* The returned string is dynamically allocated.
