2018-08-10Add proxy for syscall timeRyan Harrison
This CL adds a proxy, FXSYS_time, for the time syscall, so that a testing mechanism can be implemented. Specically there is now a flag for pdfium_test, --time=, that allows setting the time since the epoch that will be returned. This plumbed all the way down into the proxy and allows for stable results for tests that depend on getting the current time. There are other places in the code base that will need to be patched like this, that will be dealt with in follow on CLs.

2018-08-07Remove WideString::Format() from ThrowException() methods.chromium/3516Tom Sepez
No need for variadic printf-like functions, since callers can cobble arguments into a string much more simply.

2018-08-07Speculative fix for null deref above ThrowNoDefaultPropertyExceptionTom Sepez
Avoid possibility of an unterminated string or nullptr by avoiding stringviews, since the non-view classes copy and always provide a suitable result. Always use %ls and widestrings in wprintf() variants, since that combination is consistent across our platforms (%s, %S, etc. have idiosyncracies).
