[Monotone-devel] upgrade to botan 1.7.4

[Markus Schiltknecht]

Hi,

since botan 1.7.4 features some speedups for sha1, I thought I'm 
upgrading the monotone provided version right away. It is done as usual, 
see botan/README.botan-monotone.

Please check if nvm.botan runs on your machine. On my machine, the 
compiler warnings on 32bit machines seems to have gone with 1.7.4.

Baring any complaints, I'm going to land that on mainline, soon.

Regards

Markus
