Upstream commit dddccbc3ef50ac52bf00723fd2f68d98140aab80
* adds ucrtbase.def.in
* mingwex: replace mingw crt files with ucrt files
* adds missing mingw-w64 ucrt files
The rules that govern which set of files are included or excluded is
contained in the logic for tools/update_mingw.zig
this patch is from upstream, to fix -Wdeprecated-non-prototypes issues.
K&R-style has apparently been deprecated since even C89, and C2x will be
repurposing the syntax space. this warning triggers when the change would
affect the meaning of the code.
also start prefering NtDll API. so far:
* NtQueryInformationFile
* NtClose
adds a performance workaround for windows unicode conversion. but that
should probably be removed before merging
