Bug#356064: Patch for bug 356064

[Dalibor Straka <dast@panelnet.cz>]

Hello,

i have a complex patch but the two simple thoughts were
1. char scrambled_passwd[32];
is wrong. make_scrambled_passwd returns octet2hex which is longer
according to mysql sources:
buf       OUT buffer of size 2*SHA1_HASH_SIZE + 2 to store hex string

2. the hash itself changed between MySQL versions

Here is the simple patch without my macros, debug and so on...
