This enables:
* Multiple filters in the main panel and strace etc. views
* Multiple search terms
The search terms are separated by "|" and are still fixed strings
matched case-insensitive.
Added a multi flag at request of BenBE.
Adds AGRP (autogroup) and ANI (autogroup nice) columns that
report the information from /proc/PID/autogroup, as well as
handlers for '{' and '}' to change the autogroup nice value.
This is guarded by /proc/sys/kernel/sched_autogroup_enabled
such that sampling and/or changing values wont be attempted
unless the kernel feature is enabled.
Fixes: #720
Add some words about pcp-htop to the main man page, and add a
new man page describing the pcp-htop configuration files that
allow new meters and columns to be defined at runtime.
* Rename internal identifier from TTY_NR to just TTY
* Unify column header on platforms
* Use devname(3) on BSD derivate to show the actual terminal,
simplifies current FreeBSD implementation.
* Use 'unsigned long int' as id type, to fit dev_t on Linux.
Only on Solaris the terminal path is not yet resolved.
For a process with a very long command, especially with many long
command line arguments, inspecting the command and its arguments could
become inconvenient.
Meanwhile htop supports the concept of "screen", or window, which is
extended here to create a dedicated "CommandScreen", making it possible
to display the command of the selected process in a separate window
meanwhile being wrapped into multiple lines.
Another benefit of using a command screen is, the user can navigate
through the wrapped lines of the command and perform actions like
searching and filtering.
`-m` was added as short option for `--no-mouse`, this is inconsistence
to the rest of the cli since otherwise the short options to disable a
feature are capital letters. Therefore this commit renames the option to
`-M`.
This commit also documents the option in the man page.
