Adding constructor to _FX_SYSTEMTIME to resolve uninitialized read bugs found by /analyze on some error paths
Warning from /analyze was:
src\third_party\pdfium\fpdfsdk\include\fsdk_mgr.h(96) : warning C6001: Using uninitialized memory 'fxtime'.
Other error paths can also lead to reading from an uninitialized _FX_SYSTEMTIME object.
Code-gen for the constructor is small enough (four writes of zeroed EAX with VC++, less with gcc) to make putting the constructor in a .cc file unnecessary.
Approval of in-class member initialization would make this fix simpler but that has not quite been approved yet.
