Rewrite and tidy ASN1_INTEGER and ASN1_ENUMERATED handling.
Remove code duplication.
New functions to convert between int64_t and ASN.1 types without the
quirks of the old long conversion functions.
Add documentation.

+=head1 DESCRIPTION
+
+These functions convert to and from B<ASN1_INTEGER> and B<ASN1_ENUMERATED>
+structures.
+
+ASN1_INTEGER_get_int64() converts an B<ASN1_INTEGER> into an B<int64_t> type
+If successful it returns 1 and sets B<*pr> to the value of B<a>. If it fails
+(due to invalid type or the value being too big to fit into an B<int64_t> type)
+it returns 0.
+
+ASN1_INTEGER_get() also returns the value of B<a> but it returns 0 if B<a> is
+NULL and -1 on error (which is ambiguous because -1 is a legitimate value for
+an B<ASN1_INTEGER>). New applications should use ASN1_INTEGER_get_int64()
+instead.
+
+ASN1_INTEGER_set_int64() sets the value of B<ASN1_INTEGER> B<a> to the
+B<int64_t> value B<r>.
+
+ASN1_INTEGER_set() sets the value of B<ASN1_INTEGER> B<a> to the B<long> value
+B<v>.
+
+BN_to_ASN1_INTEGER() converts B<BIGNUM> B<bn> to an B<ASN1_INTEGER>. If B<ai>
+is NULL a new B<ASN1_INTEGER> structure is returned. If B<ai> is not NULL then
+the existing structure will be used instead.
+
+ASN1_INTEGER_to_BN() converts ASN1_INTEGER B<ai> into a B<BIGNUM>. If B<bn> is
+NULL a new B<BIGNUM> structure is returned. If B<bn> is not NULL then the
+existing structure will be used instead.
+
+ASN1_ENUMERATED_get_int64(), ASN1_ENUMERATED_set_int64(),
+ASN1_ENUMERATED_set(), BN_to_ASN1_ENUMERATED() and ASN1_ENUMERATED_to_BN()
+behave in an identical way to their ASN1_INTEGER counterparts except they
+operate on an B<ASN1_ENUMERATED> value.
+
+ASN1_ENUMERATED_get() returns the value of B<a> in a similar way to
+ASN1_INTEGER_get() but it returns B<0xffffffffL> if the value of B<a> will not
+fit in a long type. New applications should use ASN1_ENUMERATED_get_int64()
+instead.
+
+=head1 NOTES
+
+In general an B<ASN1_INTEGER> or B<ASN1_ENUMERATED> type can contain an
+integer of almost arbitrary size and so cannot always be represented by a C
+B<int64_t> type. However in many cases (for example version numbers) they
+represent small integers which can be more easily manipulated if converted to
+an appropriate C integer type.
+
+=head1 BUGS
+
+The ambigious return values of ASN1_INTEGER_get() and ASN1_ENUMERATED_get()
+mean these functions should be avoided if possible. They are retained for
+compatibility. Normally the ambigious return values are not legitimate
+values for the fields they represent.
+
+=head1 RETURN VALUES
+
+ASN1_INTEGER_set_int64(), ASN1_INTEGER_set(), ASN1_ENUMERATED_set_int64() and
+ASN1_ENUMERATED_set() return 1 for success and 0 for failure. They will only
+fail if a memory allocation error occurs.
+
+ASN1_INTEGER_get_int64() and ASN1_ENUMERATED_get_int64() return 1 for success
+and 0 for failure. They will fail if the passed type is incorrect (this will
+only happen if there is a programming error) or if the value exceeds the range
+of an B<int64_t> type.
+
+BN_to_ASN1_INTEGER() and BN_to_ASN1_ENUMERATED() return an B<ASN1_INTEGER> or
+B<ASN1_ENUMERATED> structure respectively or NULL if an error occurs. They will
+only fail due to a memory allocation error.
+
+ASN1_INTEGER_to_BN() and ASN1_ENUMERATED_to_BN() return a B<BIGNUM> structure
+of NULL if an error occurs. They can fail if the pased type is incorrect
+(due to programming error) or due to a memory allocation failure.
