8dcc914938 du-2: fix resource consumption when first running the plugin 
when installing / first running the plugin, it can take longer than
one munin-update call to create the $TIMEFILE. so until it is created
we assume the $LOCKFILE is not too old yet and let the first run finish
before we spawn additional processes.

16d38264aa [btrfs_device_usage] fix division by zero when btrfs pool is unhealthy 
During certain situations, a device in the btrfs pool can show a total
capacity of 0 bytes. This is aspecially true when replacing or removing a
failed disk.

This fix stops the plugin from crashing in that situation but just report
the devices percentage as unknown (U). That way other devices in the pool
stil can be monitored.

50265ccea9 Try to please linter with whitespaces arround equals. 
This does not seam logical, because it explicitly want's spaces arround equal signs when setting a variable, but you musn't use them in parameters. But well, whatever makes the linter happy.

842acaef1a Prevent escaping of internal names with leading numbers to fix graph processing 
With serials like

Node             SN                   Model                                    Namespace Usage                      Format           FW Rev  
---------------- -------------------- ---------------------------------------- --------- -------------------------- ---------------- --------
/dev/nvme0n1     285S100HTYST         KXG50ZNV512G TOSHIBA                     1         512,11  GB / 512,11  GB    512   B +  0 B   AAGA4106
/dev/nvme1n1     S4GENX0N713949       SAMSUNG MZVLB512HBJQ-00000               1         474,89  GB / 512,11  GB    512   B +  0 B   EXF7201Q

the internal names (by serial number) were rewritten to

Field 	Internal name 	Type 	Warn 	Crit 	Info
/dev/nvme0n1 	_85S100HTYST_w 	derive 	  	  	 
/dev/nvme1n1 	S4GENX0N713949_w 	derive

--> the trailing underscore in case of nvme0n1 created problems in graph processing:

[RRD ERROR] Unable to graph /var/cache/munin/www/lxdserver/....agitos.de/nvme_bytes-month.png : undefined vname c285S100HTYST_r

Therefore I added a prefix 'SN_' for internal names.

c7299aeba2 nvme: add graph for spare capacity. add support for limits 
The default limits are sort of randomly chosen.  My nvme drives report
a warning level at 10% spare capacity, so I kept that here.

a420c4eb58 smart_: renaming the file 
The destination file is a wildcard one. Therefore the C file should be
named with a trailing `_`.

2fd3eec87c Hacked together a smart_ plugin in C 
There is some trickery going on to not wakeup the disk when it's in standby

Note: this was aimed at munin-c, but was rejected since it uses a
subprocess that calls the `smartctl` tool.

f90427c32a Update for extra fields in newer kernels 
The fields have changed from 11 or 15 on recent kernels but does not effect what the plugin gathers. 
See 5.4 https://www.kernel.org/doc/html/v5.4/block/stat.html versus 4.16 https://mjmwired.net/kernel/Documentation/block/stat.txt
