Sourceforge link went away. The GitHub mirror also has the wrong path.

Replaced compatibility patches with upstream solution.

Also added an OpenSSL 1.1.0 compile fix.

+/* (From RFC1521 and draft-ietf-dnssec-secext-03.txt)
+ The following encoding technique is taken from RFC 1521 by Borenstein
+ and Freed. It is reproduced here in a slightly edited form for
+ convenience.
+
+ A 65-character subset of US-ASCII is used, enabling 6 bits to be
+ represented per printable character. (The extra 65th character, "=",
+ is used to signify a special processing function.)
+
+ The encoding process represents 24-bit groups of input bits as output
+ strings of 4 encoded characters. Proceeding from left to right, a
+ 24-bit input group is formed by concatenating 3 8-bit input groups.
+ These 24 bits are then treated as 4 concatenated 6-bit groups, each
+ of which is translated into a single digit in the base64 alphabet.
+
+ Each 6-bit group is used as an index into an array of 64 printable
+ characters. The character referenced by the index is placed in the
+ output string.
+
+ Table 1: The Base64 Alphabet
+
+ Value Encoding Value Encoding Value Encoding Value Encoding
+ 0 A 17 R 34 i 51 z
+ 1 B 18 S 35 j 52 0
+ 2 C 19 T 36 k 53 1
+ 3 D 20 U 37 l 54 2
+ 4 E 21 V 38 m 55 3
+ 5 F 22 W 39 n 56 4

+ 8 I 25 Z 42 q 59 7
+ 9 J 26 a 43 r 60 8
+ 10 K 27 b 44 s 61 9

+ 13 N 30 e 47 v
+ 14 O 31 f 48 w (pad) =
+ 15 P 32 g 49 x
+ 16 Q 33 h 50 y
+
+ Special processing is performed if fewer than 24 bits are available
+ at the end of the data being encoded. A full encoding quantum is
+ always completed at the end of a quantity. When fewer than 24 input
+ bits are available in an input group, zero bits are added (on the
+ right) to form an integral number of 6-bit groups. Padding at the
+ end of the data is performed using the '=' character.
+
+ Since all base64 input is an integral number of octets, only the
+ -------------------------------------------------
+ following cases can arise:
+
+ (1) the final quantum of encoding input is an integral
+ multiple of 24 bits; here, the final unit of encoded
+ output will be an integral multiple of 4 characters
+ with no "=" padding,
+ (2) the final quantum of encoding input is exactly 8 bits;
+ here, the final unit of encoded output will be two
+ characters followed by two "=" padding characters, or
+ (3) the final quantum of encoding input is exactly 16 bits;
+ here, the final unit of encoded output will be three
+ characters followed by one "=" padding character.

A 65-character subset of US-ASCII is used, enabling 6 bits to be
represented per printable character. (The extra 65th character, "=",
is used to signify a special processing function.)
The encoding process represents 24-bit groups of input bits as output
strings of 4 encoded characters. Proceeding from left to right, a
24-bit input group is formed by concatenating 3 8-bit input groups.
These 24 bits are then treated as 4 concatenated 6-bit groups, each
of which is translated into a single digit in the base64 alphabet.
Each 6-bit group is used as an index into an array of 64 printable
characters. The character referenced by the index is placed in the
output string.

Special processing is performed if fewer than 24 bits are available
at the end of the data being encoded. A full encoding quantum is
always completed at the end of a quantity. When fewer than 24 input
bits are available in an input group, zero bits are added (on the
right) to form an integral number of 6-bit groups. Padding at the
end of the data is performed using the '=' character.
Since all base64 input is an integral number of octets, only the
following cases can arise:
(1) the final quantum of encoding input is an integral
multiple of 24 bits; here, the final unit of encoded
output will be an integral multiple of 4 characters
with no "=" padding,
(2) the final quantum of encoding input is exactly 8 bits;
here, the final unit of encoded output will be two
characters followed by two "=" padding characters, or
(3) the final quantum of encoding input is exactly 16 bits;
here, the final unit of encoded output will be three
characters followed by one "=" padding character.

/* (From RFC1521 and draft-ietf-dnssec-secext-03.txt)
The following encoding technique is taken from RFC 1521 by Borenstein
and Freed. It is reproduced here in a slightly edited form for
convenience.
A 65-character subset of US-ASCII is used, enabling 6 bits to be
represented per printable character. (The extra 65th character, "=",
is used to signify a special processing function.)
The encoding process represents 24-bit groups of input bits as output
strings of 4 encoded characters. Proceeding from left to right, a
24-bit input group is formed by concatenating 3 8-bit input groups.
These 24 bits are then treated as 4 concatenated 6-bit groups, each
of which is translated into a single digit in the base64 alphabet.
Each 6-bit group is used as an index into an array of 64 printable
characters. The character referenced by the index is placed in the
output string.
