openssl/util/mkdef.pl
Richard Levitte e66b62b86e util/mkdef.pl: handle line terminators correctly 
When parsing the header files, mkdef.pl didn't clear the line
terminator properly.  In most cases, this didn't matter, but there
were moments when this caused parsing errors (such as CRLFs in certain
cases).

Fixes #4267

# generate a .def file
#
# It does this by parsing the header files and looking for the
# prototyped functions: it then prunes the output.
#
# Intermediary files are created, call libcrypto.num and libssl.num,
# The format of these files is:
#
# routine-name nnnn vers info
#
# The "nnnn" and "vers" fields are the numeric id and version for the symbol
# respectively. The "info" part is actually a colon-separated string of fields
# with the following meaning:
#
# existence:platform:kind:algorithms
#
# - "existence" can be "EXIST" or "NOEXIST" depending on if the symbol is
# found somewhere in the source,
# - "platforms" is empty if it exists on all platforms, otherwise it contains
# comma-separated list of the platform, just as they are if the symbol exists
# for those platforms, or prepended with a "!" if not. This helps resolve
# symbol name variants for platforms where the names are too long for the
# compiler or linker, or if the systems is case insensitive and there is a
# clash, or the symbol is implemented differently (see
# EXPORT_VAR_AS_FUNCTION). This script assumes renaming of symbols is found
# in the file crypto/symhacks.h.
# The semantics for the platforms is that every item is checked against the
# environment. For the negative items ("!FOO"), if any of them is false
# (i.e. "FOO" is true) in the environment, the corresponding symbol can't be
# used. For the positive items, if all of them are false in the environment,
# the corresponding symbol can't be used. Any combination of positive and
# negative items are possible, and of course leave room for some redundancy.
# - "kind" is "FUNCTION" or "VARIABLE". The meaning of that is obvious.
# - "algorithms" is a comma-separated list of algorithm names. This helps
# exclude symbols that are part of an algorithm that some user wants to
# exclude.
