Jussi Kivilinna e8142cc69a g10/armor: optimize binary to radix64 conversion
* g10/armor.c (bintoasc): Change to read-only.
(initialize): Use const pointer for 'bintoasc'.
(armor_output_buf_as_radix64): New function for faster binary to
radix64 conversion.
(armor_filter): Use new conversion function.
--

This patch adds faster binary to radix64 conversion to speed up
armored encryption.

Benchmark results below, tested on Intel Core i7-4790K (turbo off).
Encrypted 2 GiB through pipe to ramfs file using AES128. Decrypt
ramfs file out through pipe to /dev/null.
