Add define guards to avoid multi-inclusion This header files are included by multiple other headers. It's better to add define guards to prevent multi-inclusion. Adhere to the coding style, all preprocessor directives inside the guards gain a space.

PROV: Add the beginning of a DER writing library This library is meant to be small and quick. It's based on WPACKET, which was extended to support DER writing. The way it's used is a bit unusual, as it's used to write the structures backward into a given buffer. A typical quick call looks like this: /* * Fill in this structure: * * something ::= SEQUENCE { * id OBJECT IDENTIFIER, * x [0] INTEGER OPTIONAL, * y [1] BOOLEAN OPTIONAL, * n INTEGER * } */ unsigned char buf[nnnn], *p = NULL; size_t encoded_len = 0; WPACKET pkt; int ok; ok = WPACKET_init_der(&pkt, buf, sizeof(buf) && DER_w_start_sequence(&pkt, -1) && DER_w_bn(&pkt, -1, bn) && DER_w_boolean(&pkt, 1, bool) && DER_w_precompiled(&pkt, -1, OID, sizeof(OID)) && DER_w_end_sequence(&pkt, -1) && WPACKET_finish(&pkt) && WPACKET_get_total_written(&pkt, &encoded_len) && (p = WPACKET_get_curr(&pkt)) != NULL; Reviewed-by: Matt Caswell <matt@openssl.org> (Merged from https://github.com/openssl/openssl/pull/11450)
