Fast duplication check in inodes processing.
...
Instead of encoding a JSON string of each connection (non-trivial at high
connection volumes) we can use the connTmp struct for map look-ups if we
eliminate the unused `uids` field.
Also switches to using the empty struct instead of bool for zero memory
overhead.

Add ConnectionsMax function that limits connections per pid.
...
The goal is to improve performance of connection fetching connections across
all processes when some processes can have several hundred or thousands of file
descriptors. Right now when you have many thousands of fds the process spends
lots of time inside the syscalls from Readdir and Readlink.
The public API works as before with two new functions:
- `ConnectionsMax`
- `ConnectionsPidMax`
Each function takes an additional int argument that sets the max number of fds
read per process.

common: rename package common to internal/common. Add ENV helper funcs.
...
Package common wasn't used for public functions. Place it in an
internal directory to prevent other packages from using.
Remove the distributed references to "HOST_PROC" and "HOST_SYS"
consts and combine into a common function. This also helps so that
if a env var is defined with a trailing slash all will continue to
work as expected.
Fixes #100

the default value.
