Like OpenSSL, move some text from ERR(3) to the fitting page ERR_put_error(3).
Merge documentation of ERR_add_error_vdata(3) from OpenSSL.
Drop useless statement about void functions returning no values.

 The remainder of this section is of interest only if you want to add new
 error codes to OpenSSL or add error codes from external libraries.
-.Ss Reporting errors
-Each sub-library has a specific macro
-.Fn XXXerr f r
-that is used to report errors.
-Its first argument is a function code
-.Dv XXX_F_* ;
-the second argument is a reason code
-.Dv XXX_R_* .
-Function codes are derived from the function names
-whereas reason codes consist of textual error descriptions.
-For example, the function
-.Fn ssl23_read
-reports a "handshake failure" as follows:
-.Pp
-.Dl SSLerr(SSL_F_SSL23_READ, SSL_R_SSL_HANDSHAKE_FAILURE);
-.Pp
-Function and reason codes should consist of upper case characters,
-numbers and underscores only.
-The error file generation script translates function codes into function
-names by looking in the header files for an appropriate function name.
-If none is found it just uses the capitalized form such as "SSL23_READ"
-in the above example.
-.Pp
-The trailing section of a reason code (after the "_R_") is translated
-into lower case and underscores changed to spaces.
 .Pp
 When you are using new function or reason codes, run
 .Sy make errors .
 The necessary
 .Sy #define Ns s
 will then automatically be added to the sub-library's header file.
-.Pp
-Although a library will normally report errors using its own specific
-.Fn XXXerr
-macro, another library's macro can be used.
-This is normally only done when a library wants to include ASN.1 code
-which must use the
-.Fn ASN1err
-macro.
 .Ss Adding new libraries
 When adding a new sub-library to OpenSSL, assign it a library number
 .Dv ERR_LIB_XXX ,
