Don't rely on embedded flag to free strings correctly: it wont be

In 1.1.0 we only allowed a strictly increasing version number in the *.num
files, i.e. you could never introduce a symbol at the end of the *.num file
with a lower version number than the one preceding it. This made sense for
1.1.0. However in master we may be introducing symbols for backport to
1.1.0. Therefore it is ok in master to have a symbol for version 1.1.0c
coming after a symbol for version 1.1.1.

This commit fixes the check in mkdef.pl to be a bit looser to allow this.

If len == 0 in a call to ERR_error_string_n() then we can read beyond the
end of the buffer. Really applications should not be calling this function
with len == 0, but we shouldn't be letting it through either!

Looking for something starting with '-Wl,-rpath,' isn't good enough,
as someone might give something like '-Wl,--enable-new-dtags,-rpath,/PATH'.
Looking for ',-rpath,' should be safe enough.

We could remove the preloading stuff entirely, but just in case the
user has chosen to given RPATH setting arguments at configuration,
we'd better make sure testing will still work.  Fair warning, there
are some configuration options that do not work with preloaded OpenSSL
libraries, such as the sanity checking ones.

Make Configure recognise -rpath and -R to support user added rpaths
for OSF1 and Solaris.  For convenience, add a variable LIBRPATH in the
Unix Makefile, which the users can use as follows:

Before OpenSSL 1.1.0, binaries were installed in a non-standard
location by default, and runpath directories were therefore added in
those binaries, to make sure the executables would be able to find the
shared libraries they were linked with.

With OpenSSL 1.1.0 and on, binaries are installed in standard
directories by default, and the addition of runpath directories is
therefore not needed any more.

Note that it relies on a trick from Configure, where file names for
object files made from C++ source get '.cc' replaced with '_cc.o' to
recognise them.  This is needed so the correct compiler is used when
linking binaries.

A note: this will form object file names by changing '.cc' to
'_cc.o'.  This will permit other configuration code to recognise these
object files were built for C++ rather than C.

The prevailing style seems to not have trailing whitespace, but a few
lines do. This is mostly in the perlasm files, but a few C files got
them after the reformat. This is the result of:

  find . -name '*.pl' | xargs sed -E -i '' -e 's/( |'$'\t'')*$//'
  find . -name '*.c' | xargs sed -E -i '' -e 's/( |'$'\t'')*$//'
  find . -name '*.h' | xargs sed -E -i '' -e 's/( |'$'\t'')*$//'

Then bn_prime.h was excluded since this is a generated file.

Note mkerr.pl has some changes in a heredoc for some help output, but
other lines there lack trailing whitespace too.
