autofs-5.0.9 - amd lookup add cache partial match functions

Partial key matching is used for amd. A prefix is possibly added to the key
|
|
|
4d476f |
and if the map entry key has a trailing /* and matches the initial part of
|
|
|
4d476f |
the key+prefix the match succeeds.
|
|
|
4d476f |
|
|
|
4d476f |
Update the existing partial match functions to help with this.
