* Initialize SoftAP DhcpServer object on demand
Remove dependency on global ctor, and just construct the object when
someone asks us to do it. Only dependency right now is netif_git, which
is expected to be initialized by the lwip code some time before
dhcps_start happens.
Removing ip_info from begin(), since we never reference later on.
Also removing the specific check for netif id and simplify the ctors.
Update tests and recover old nonos-sdk dhcps functions that were not implemented.
* nonos helpers have a separate header
* wifi ap needs this anyway, simplify sketch includes
* missing example
* existing name :/
* trying to fix header dependency
* restyle
* not a c header
* no need to init
* move dhcp server getter to WiFi
more... arduino'ish? we ahve object as namespace, plus everything else
related to softAP is there
redundant includes, redundant mock impl (out-of-scope here to fix)
* ...move things back, still expose as WiFi method
* review fix
* include -nonos header in wifi lib though
* no more lwip include
* style
* need mock dhcpserver instance
The key functions added are:
`bool enableForwarder(const String &domainName=emptyString, const IPAddress &dns=uint32_t)0)`
If specified, `enableForwarder` will update the `domainName` that is used to match DNS request to this AP's IP Address. A non-matching request will be forwarded to the DNS server specified by `dns`.
Returns `true` on success.
Returns `false`,
* when forwarding `dns` is not set, or
* unable to allocate resources for managing the DNS forward function.
`void disableForwarder(const String &domainName=emptyString, bool freeResources=false)`
`disableForwarder` will stop forwarding DNS requests. If specified, updates the `domainName` that is matched for returning this AP's IP Address.
Optionally, resources used for the DNS forward function can be freed.
