string: ensure string included

Latest upstream yocto appears to have removed a free include of string.
This is causing compile failures for files which do not include it
properly.

Policy table lookup enhancements

Adds support for 2 new lookups:

1) Use the called out device path as the search modifier.
2) Use the called out FRU + the severity of the PEL error
extracted from the ESEL metadata in the log as the
search modifier.

If a match isn't found in the policy table with these modifiers,
then the code will search again using the existing modifier checks.

Note:
PEL = Platform Event Log. This is the logging standard used
by OpenPower host firmware. The PEL contents are in
the ESEL data in the AdditionalData property in an
OpenBMC error log entry.

Ideally would have done this from the beginning,

Not all details entries have a modifier, and if it is empty
it will match on anything.

Add policy::Table class

This class holds the error log policy data defined by
IBM's service people. The raw data is stored in a JSON
file on the BMC, and loaded into the class on construction.

The policy data is a map of error messages (i.e. the
xyz.openbmc_project.Foo.Error.Bar strings) to a list of
policy details structures.

Each details structure has:
* a search modifier - used to find the specific details
entry for a specific error log message.
* a message - a customer facing description of the error
* an event ID - an ID defined by IBM that can be used to
locate information about the error online.

An example of an entry of the JSON data it consumes is:
{
"dtls":[
{
"CEID":"ID 1",
"mod":"mod 1",
"msg":"Error 1"
},
{
"CEID":"ID 2",
"mod":"mod 2",
"msg":"Error 2 "
}
],
"err":"xyz.openbmc_project.Error.Test1"
}

A future commit will add the ability to find an entry.
