updspapi: Add a stub implementation of UpdSpSetDynamicStringA.

[Hans Leidekker]

UpdSpSetDynamicStringA is another undocumented API called by the IE7
installer. Luckily the installer log provides some useful information.

Before stubbing:

4.676: ProcessDynamicStrings:  CustomStringTable for DownloadedProgramFiles returned D
4.676: ProcessDynamicStrings:  UpdSpSetDynamicString failed on DownloadedProgramFiles to D:  0x0
4.677: DoInstallation:  ProcessDynamicStrings failed:  0x0

Which suggests at least two string arguments. A first draft stub and a +relay
log reveals that the first argument is not a string but a pointer to an inf
structure (ie. an HINF), since this value is also passed as the first argument
to a function documented to take an HINF in that position.

The second two parameters do appear to be strings; dumping them yields
"DownloadedProgramFiles" and "D". Finally, returning 1 instead of 0 causes
this message to appear in the log instead:

4.393: ProcessDynamicStrings:  CustomStringTable for DownloadedProgramFiles returned D
4.393: ProcessDynamicStrings:  all %DownloadedProgramFiles% replaced with D.
