Prior to autoconf 2.13, AC_CHECK_TYPE took two arguments, the type
to check and the a default type to use if that type wasn't defined.
This usage has been deprecated since 2.13, and the AC_CHECK_TYPE
macro itself now behaves differently. Whilst there is a compatibility
mode, the autoconf documentation discourages its use.
We also have an occurence of a slightly more modern AC_CHECK_TYPE,
where we explicitly #define a default value if one isn't provided.
The autoconf manual also discourages this form, however, in favour
of using AC_CHECK_TYPES, and placing suitable typedefs in an
external header file.
Modify our code so we do things in the recommended way.

The use of strlen, strcat, strcpy, strncpy and sprintf in
src\WINNT\afsd\fs.c does not effectively protect against buffer
overruns and string truncation errors. This patchset replaces
their use with StringCbLen, StringCbCat, StringCbCopy,
StringCbCopyN, StringCbCopyEx and StringCbPrintf respectively from
strsafe.h.
The functions sscanf, fscanf and scanf do not check for the size of
the parameters so it is prone to buffer overruns. These functions
can be replaced by sscanf_s, fscanf_s, scanf_s when the Visual Studio
compiler version is 1400 or greater. Also memcpy will be replaced
by memcpy_s which will check for the size of the destination buffer.
In all cases, failure conditions are handled.

platform specific vcache operations:
*) osi_TryEvictVCache handles the decision of whether a vcache can
be evicted or not, and does so if required
*) osi_NewVnode allocates a new vnode
*) osi_PrePopulateVCache does the necessary population of the
vcache, before it's threaded onto the VLRUQ and associated hash

*) osi_AttachVnode handles attaching an OS vnode to our vcache,
where that is necessary
*) osi_PostPopulateVCache handles the vcache population that must
