As described in https://github.com/openssl/openssl/issues/9187, the
loading of PEM certificates sometimes fails if a line of base64
content has the length of a multiple of 254.
The problem is in get_header_and_data(). When such a line with a
length of 254 (or a multiple) has been read, the next read will
only read a newline. Due to this get_header_and_data() expects to be
in the header not in the data area. This commit fixes that by checking
if lines have been read completely or only partially. In case of a
previous partial read, a newline will be ignored.

AGL has a history of pointing out the idiosynchronies/laxness of the
openssl PEM parser in amusing ways. If we want this functionality to
stay present, we should test that it works.

Generate a fresh certificate and DSA private key in their respective PEM
files. Modify the resulting ASCII in various ways so as to produce input
files that might be generated by non-openssl programs (openssl always
generates "standard" PEM files, with base64 data in 64-character lines
except for a possible shorter last line).
Exercise various combinations of line lengths, leading/trailing
whitespace, non-base64 characters, comments, and padding, for both
unencrypted and encrypted files. (We do not have any other test coverage
that uses encrypted files, as far as I can see, and the parser enforces
different rules for the body of encrypted files.)
Add a recipe to parse these test files and verify that they contain the
expected string or are rejected, according to the expected status.
Some of the current behavior is perhaps suboptimal and could be revisited.
