All `.pxi` files have the warning to not edit directly, so why not
have Git ignore any changes made there? In addition, this PR
deletes all of the `.pxi` files from the codebase because they are
automatically generated by the `.pxi.in` files

This commit fixes a bug where `read_csv` failed when given a file with
a multiindex header and empty content. Because pandas reads index
names as a separate line following the header lines, the reader looks
for the line with index names in it. If the content of the dataframe
is empty, the reader will choke. This bug surfaced after
https://github.com/pandas-dev/pandas/issues/6618 stopped writing an
extra line after multiindex columns, which led to a situation where
pandas could write CSV's that it couldn't then read. This commit
changes that behavior by explicitly checking if the index name row
exists, and processing it correctly if it doesn't.

(cherry picked from commit f862b52e75)
In python 3.6, the CALL_FUNCTION handling was updated. One change is
that when calling a C function from a python function python now
counts the reference owned by the argument tuple. This means that
move was always seeing objects with two references instead of the
expected one. Python 3.6 also removed a copy in the argument tuple
when *unpacking functions. This means that if a user does: tuple =
(create_string(),) move_into_mutable_buffer(*tuple) where
create_string() creates a string object with one reference then we
will fail to raise a BadMove even though the user could later retrieve
that string with tuple[0]. There is no way to detect this case so this
patch adds a warning to the docstring advising against star unpacking.
xref: #14679 I played around with removing the extra reference that
was added in 3.6 but it looks like playing with borrowed refs
everywhere will be a bit tricky. This change should clear things up
for 3.6 while continuing to work for older versions. In 3.6 you
__could__ get a shared mutable string from this but you need to try
pretty hard for it.
