ConvertStringSecurityDescriptorToSecurityDescriptor() is used when
creating the initial connection pipe. Because this is done from inside
DllMain(), we cannot use advapi32 (where this function is). Instead,
save the binary representation of the self-relative SECURITY_DESCRIPTOR.
It is conceivable that this could change, but unlikely as this is the
same blob that would be stored on a file in NTFS.
Another potential approach would be to not make the pipe available to
all integrity levels here, and instead modify the Chromium sandbox code
to allow a specific pipe name prefix that would have to correspond with
the pipe name that Crashpad creates.
Similarly, UuidCreate() (used when initializing the database) is in a
DLL that can't be loaded early, so use the Linux/Android implementation
on Windows too.
