Remove MD4 support from LibreSSL.

MD4 should have been removed a long time ago.  Also, RFC 6150 moved it to
historic in 2011.  Rides the major crank from removing SHA-0.

Discussed with many including beck@, millert@, djm@, sthen@
ok jsing@, input + ok bcook@

 =head1 DESCRIPTION
 
-MD2, MD4, and MD5 are cryptographic hash functions with a 128 bit output.
+MD5 is a cryptographic hash function with a 128 bit output.
 
-MD2(), MD4(), and MD5() compute the MD2, MD4, and MD5 message digest
-of the B<n> bytes at B<d> and place it in B<md> (which must have space
-for MD2_DIGEST_LENGTH == MD4_DIGEST_LENGTH == MD5_DIGEST_LENGTH == 16
+MD5() computes the MD5 message digest of the B<n> bytes at B<d> and
+places it in B<md> (which must have space for MD5_DIGEST_LENGTH == 16
 bytes of output). If B<md> is NULL, the digest is placed in a static
 array.
 
 The following functions may be used if the message is not completely
 stored in memory:
 
-MD2_Init() initializes a B<MD2_CTX> structure.
-
-MD2_Update() can be called repeatedly with chunks of the message to
-be hashed (B<len> bytes at B<data>).
-
-MD2_Final() places the message digest in B<md>, which must have space
-for MD2_DIGEST_LENGTH == 16 bytes of output, and erases the B<MD2_CTX>.
-
-MD4_Init(), MD4_Update(), MD4_Final(), MD5_Init(), MD5_Update(), and
-MD5_Final() are analogous using an B<MD4_CTX> and B<MD5_CTX> structure.
-
 Applications should use the higher level functions
 L<EVP_DigestInit(3)|EVP_DigestInit(3)>
 etc. instead of calling the hash functions directly.
 
 =head1 NOTE
 
-MD2, MD4, and MD5 are recommended only for compatibility with existing
-applications. In new applications, SHA-1 or RIPEMD-160 should be
-preferred.
+MD5 is recommended only for compatibility with legacy applications.
+In new applications, SHA-2 should be preferred.
 
 =head1 RETURN VALUES
 
-MD2(), MD4(), and MD5() return pointers to the hash value.
+MD5() returns a pointer to the hash value.
 
-MD2_Init(), MD2_Update(), MD2_Final(), MD4_Init(), MD4_Update(),
-MD4_Final(), MD5_Init(), MD5_Update(), and MD5_Final() return 1 for
-success, 0 otherwise.
+MD5_Init(), MD5_Update(), and MD5_Final() return 1 for success, 0

 =head1 DESCRIPTION
 
-MD2, MD4, and MD5 are cryptographic hash functions with a 128 bit output.
+MD5 is a cryptographic hash function with a 128 bit output.
 
-MD2(), MD4(), and MD5() compute the MD2, MD4, and MD5 message digest
-of the B<n> bytes at B<d> and place it in B<md> (which must have space
-for MD2_DIGEST_LENGTH == MD4_DIGEST_LENGTH == MD5_DIGEST_LENGTH == 16
+MD5() computes the MD5 message digest of the B<n> bytes at B<d> and
+places it in B<md> (which must have space for MD5_DIGEST_LENGTH == 16
 bytes of output). If B<md> is NULL, the digest is placed in a static
 array.
 
 The following functions may be used if the message is not completely
 stored in memory:
 
-MD2_Init() initializes a B<MD2_CTX> structure.
-
-MD2_Update() can be called repeatedly with chunks of the message to
-be hashed (B<len> bytes at B<data>).
-
-MD2_Final() places the message digest in B<md>, which must have space
-for MD2_DIGEST_LENGTH == 16 bytes of output, and erases the B<MD2_CTX>.
-
-MD4_Init(), MD4_Update(), MD4_Final(), MD5_Init(), MD5_Update(), and
-MD5_Final() are analogous using an B<MD4_CTX> and B<MD5_CTX> structure.
-
 Applications should use the higher level functions
 L<EVP_DigestInit(3)|EVP_DigestInit(3)>
 etc. instead of calling the hash functions directly.
 
 =head1 NOTE
 
-MD2, MD4, and MD5 are recommended only for compatibility with existing
-applications. In new applications, SHA-1 or RIPEMD-160 should be
-preferred.
+MD5 is recommended only for compatibility with legacy applications.
+In new applications, SHA-2 should be preferred.
 
 =head1 RETURN VALUES
 
-MD2(), MD4(), and MD5() return pointers to the hash value.
+MD5() returns a pointer to the hash value.
 
-MD2_Init(), MD2_Update(), MD2_Final(), MD4_Init(), MD4_Update(),
-MD4_Final(), MD5_Init(), MD5_Update(), and MD5_Final() return 1 for
-success, 0 otherwise.
