Avoid NULL pointer dereference

Function readbuffer_gets() misses some of the initial checks of its
arguments. Not checking them can lead to a later NULL pointer
dereferences.

Function readbuffer_gets() misses some of the initial checks of its

dereferences.

The checks are now unified with the checks in readbuffer_read()
function.

Fix DER reading from stdin for BIO_f_readbuffer

Fixes #14559

The intitial implementation of the gets() function tried using the next bio's gets() function.
For a file BIO this returned incorrect data for binary data containing 0x00.
Just buffering all data during gets() did not work however since some
applications open and close the bio multiple times when dealing with pem
files containing multiple entries.. This does not work
when reading from stdin unless the data if buffered one byte at a time.

not support these methods. The main use case for this is file/fd BIO's
that use stdin.

This works for stdin taken from input redirection (command < file),
and stdin via pipe (cat file | command).
