Standardize apps use of -rand, etc.

Standardized the -rand flag and added a new one:
    -rand file...
            Always reads the specified files
    -writerand file
            Always writes to the file on exit

For apps that use a config file, the RANDFILE config parameter reads
the file at startup (to seed the RNG) and write to it on exit if
the -writerand flag isn't used.

Ensured that every app that took -rand also took -writerand, and
made sure all of that agreed with all the documentation.

OSSL_STORE: Treat URIs as files first (with exceptions), then as full URIs

To handle paths that contain devices (for example, C:/foo/bar.pem on
Windows), try to "open" the URI using the file scheme loader first,
and failing that, check if the device is really a scheme we know.

The "file" scheme does the same kind of thing to pick out the path
part of the URI.

An exception to this special treatment is if the URI has an authority
part (something that starts with "//" directly after what looks like a
scheme).  Such URIs will never be treated as plain file paths.

STORE 'file' scheme loader: fix try_decode_params() to check ambiguity

The way try_decode_params works in raw more, it would take the first ASN1
that could decode and return a STORE_INFO with the resulting EVP_PKEY.
This change has it go through all the matching ASN1 methods and properly
check if there's more than one match, i.e. an ambiguity.

Error out when forcing an unsupported TLS version

If the result of a SSL_{CTX_,}set_{min,max}_proto_version() call
leaves the min and max version identical, and support for that version
is compiled out of the library, return an error.  Such an object has
no hope of successfully completing a handshake, and this error may
be easier to decipher than the resulting handshake failure.

Improve BN_CTX documentation

Since BN_CTX_init() is gone, all calls use BN_CTX_new().  Also,
essentially all consumers will use BN_CTX_start()/BN_CTX_end(),
so make that more clear from the BN_CTX_new() man page.

Fix small UI issues

- in EVP_read_pw_string_min(), the return value from UI_add_* wasn't
  properly checked
- in UI_process(), |state| was never made NULL, which means an error
