ENH: Ignoring empty lines in files

[holocronweaver]

Currently pandas preserves empty lines when reading CSV files. I think the default should be to ignore empty lines, with a possible optional parameter to retain them.

Implementing this in the C and Python parsers should be an easy extension of my work on #2685 , but I wanted some feedback before I do so.

+1 This sounds like an excellent idea!

Will your PR fix #4623?

@timmie were you working on something like this?

#4340 is about the content before data is read.
I assume this issue is about ignoring within the data part.
So answer is no.

I have an issue with more than one blank line at the end of csv files. This tends to lead to hard to track down problems with the produced dataframes, but with no complaints from the reader.

It would be good if read_csv ignored a continuous block of blank line at the end of a csv file.

@holocronweaver any thoughts/progress on impl of this?
