The previous test certificates contained RSA keys of only 1024 bits.
However, RSA claims that 1024-bit RSA keys are likely to become
crackable some time before 2010. The NIST recommends at least 2048-bit
keys for RSA for now.

Better use full 2048 also for testing.

On Windows, the read function from <io.h> is used, which has its byte
count parameter as unsigned int instead of size_t.

- Use memcpy instead of strncpy to copy a string without termination,
  since gcc8 warns about using strncpy to copy as many bytes from a
  string as its length.

Rather than jumping backwards to where failure cleanup happens
to be performed, move the failure case to end of the function
where it is expected per existing coding convention.

If the formatting fails, we error out on a fatal error and
clean up on the way out. The array was however freed within
the wrong scope and was thus never freed in case the cookies
were written to a file instead of STDOUT.

Closes #2957

Expired cookies have already been purged at a later expiration time
before this check, so remove the redundant check.

Exit the realloc() loop if the response turns out ridiculously large to

Sometimes it may be considered a security risk to load an external
OpenSSL configuration automatically inside curl_global_init(). The
configuration option --disable-ssl-auto-load-config disables this
automatism. The Windows build scripts winbuild/Makefile.vs provide a
corresponding option ENABLE_SSL_AUTO_LOAD_CONFIG accepting a boolean
value.

Setting neither of these options corresponds to the previous behavior
loading the external OpenSSL configuration automatically.

... and add "MAILINDEX".

As described in #2789, this is a suggested solution.  Changing UID=xx to
actually get mail with UID xx and add "MAILINDEX" to get a mail with a
special index in the mail box (old behavior).  So MAILINDEX=1 gives the
first non deleted mail in the mail box.
