Remove unused Git attributes ident

The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.

In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.

This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.

base64_decode: remove redundant code

case 1 is already handled in the first lines of the for loop;
it would only be entered in the invalid case where the string
continues past the defined length (ch != 0 but length-- == 0).

case 2 and case 3 are redundant, since k >= j and later the
string is truncated to j characters anyway.
