The exclusion of SHA1 for X509 signatures is not obvious as the "intuative"
idea is that SHA1 should have 80 security bits. However the security bits
of SHA1 are explicitly set to 63 to avoid the it being strong enough for
security level 1. x509_set.c has the comment:
/*
* SHA1 and MD5 are known to be broken. Reduce security bits so that
* they're no longer accepted at security level 1.
* The real values don't really matter as long as they're lower than 80,
* which is our security level 1.

This is the length of the tag they use and should be considered an upper bound
on their strength.
This lowers their security strength to level 0.

Today, majority of web-browsers reject communication as allowed by the
security level 1. Instead key sizes and algorithms from security level
2 are required. Thus remove the now obsolete warning against using
security levels higher than 1. For example Ubuntu, compiles OpenSSL
with security level set to 2, and further restricts algorithm versions
available at that security level.

While stereotyped repetitions are frowned upon in literature, they
serve a useful purpose in manual pages, because it is easier for
the user to find certain information if it is always presented in
the same way. For that reason, this commit harmonizes the varying
formulations in the HISTORY section about which functions, flags,
etc. were added in which OpenSSL version.
It also attempts to make the pod files more grep friendly by
avoiding to insert line breaks between the symbol names and the
corresponding version number in which they were introduced
(wherever possible). Some punctuation and typographical errors
were fixed on the way.

I tried hard to keep the lines at 80 characters or less, but in a few
cases I had to punt and just indented the subsequent lines by 4 spaces.
A few well-placed typedefs for callback functions would really help, but
these would be part of the API, so that's probably for later.
I also took the liberty of inserting empty lines in overlong blocks to
provide some visual space.
