Make CSV Data Set Config use specified encoding

[asfimport]

Alf Hogemark (Bug 41704):
Currently, the CSV Data Set Config does not allow the user to specify what
character set encoding is used in the csv file which contains the test data to
use in a Jmeter test.

Therefore, the csv data files must have the default system character set
encoding. Currently, it is the java class FileReader which is used to read the
file, and that assumes the default platform character set encoding for the file.

It would be useful to be able to specify the character set encoding used in a
csv data file, so that you can use different encodings. That will also allow you
to use the same data files on different operating systems, which can have
different default character set encodings.

Thanks for the contribution.

Looks mostly OK.

However, it changes the public API of the FileServer class, as the reserveFile
method now has an extra parameter. This could cause 3rd party applications to
fail. Easy enough to resolve by overloading the method.

Also, the encoding could perhaps be added to the FileEntry class instead of
using a separate HashMap.

I'll see about adding this - no need to recreate the patch at present.
