v0.9.0 does not build on the Arduino 101 and Due

/Users/smistry/Documents/Arduino/libraries/WiFi101/src/WiFiMdnsResponder.cpp: In member function ‘bool WiFiMDNSResponder::parseRequest()’:
/Users/smistry/Documents/Arduino/libraries/WiFi101/src/WiFiMdnsResponder.cpp:152:61: error: ‘memcmp_P’ was not declared in this scope
     if (memcmp_P(request, expectedRequestHeader, HEADER_SIZE) == 0 &&            // request header match
                                                             ^

         strncasecmp(name.c_str(), (char*)requestName, requestNameLength) == 0 && // name match

1. The Arduino 101 does not provide memcmp_P in avr/pgmspace.h

2. There is no strncasecmp method.

The AVR and SAMD cores build fine, however SAM core also experiences 1).

@facchinm any thoughts on how to proceed with this? This breakage was introduced in #47.

I believe that porting SAMD's avr/pgmspace.h to SAM and Curie will be the best long term solution 👍

@facchinm I've submitted the following pull requests:

• Sync SAM avr/pgmspace.h entries with SAMD core arduino/Arduino#4820
• Sync avr/pgmspace.h entries with SAMD core arduino/ArduinoCore-arc32#159
• Add strings.h include for non-AVR platforms #52

Once all 3 are merged we can close this issue.

The upstream changes have been merged and released (1.0.6 for the 101 core, 1.6.8 for SAM core).

Travis CI build is also now passing for the 101 and SAM.
