* Replace <sys/param.h> with <limits.h> and other less dirty headers wherederaadt2015-01-161-4/+3
| | | | | | | | | possible. Annotate <sys/param.h> lines with their current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)

| | | | | | case of out of memory conditions, Plan B can step in. In many cases, NULL value is not properly handled, so use xstrdup here (it's outside Plan A/B patching, which means that even Plan B relies on successful operations).
* Fix division by zero for files with long lines (> 1024) in Plan B modetobias2014-12-091-19/+37

| | | | | | | unmaintainable). these days, people use source. these id's do not provide any benefit, and do hurt the small install media (the 33,000 line diff is essentially mechanical) ok with the idea millert, ok dms
