Returns TRUE if the experimental HTTP/HTTPS virtual file system was compiled
in (libcurl detected at build time), FALSE otherwise. This is a compile-time
indicator; even if TRUE the VFS might still fail to register at runtime on
unusual platforms, in which case sqliteHasHttpVFS() is the definitive
runtime capability probe.
Details
sqliteHasHttpVFS() performs a lazy registration attempt when the VFS
is compiled in but not yet registered. If the HTTP VFS was not compiled in,
calls to sqliteRemote() will error.
