* Driver for Sensirion SHT3x sensor added
This is a driver for Sensirion SHT3x temperature and humidity sensors
connected via I2C.
This commit is a rebasing and contains some interface changes based on
the review from @ourairquality.

Additional include to satisfy the Travis CI test build

README.md has been shortened
* SHT3x driver - small changes
* SHT3x driver - small changes
- crc8 lookup table is now static to be held in flash memory
- special handling for the timer overflow in sht3x_is_measuring removed
- initialization reduced to availability check
* SHT3x driver - some small changes
- crc8 lookup table is now static to be held in flash memory
- special handling for the timer overflow in sht3x_is_measuring removed
- some whitespace removed

for vTaskDelay (documentation and examples changed accordingly)

SHT3x driver changes
- additional include to satisfy the Travis CI test build
- README.md has been shortened
- special handling for the timer overflow in sht3x_is_measuring removed
- some whitespaces removed
- crc8 computation changed to a non table lookup version
- measurement duration is now given in ticks and can be used directly
for vTaskDelay (documentation and examples changed accordingly)
- number of ticks for measurement duration takes now into account
portTICK_PERIOD_MS
- clock stretching disabled on sensor to avoid blocking when data are
not ready to read
- calculation of maesurement duration adds now one and a half ticks to
be sure that measurement duration is not too short
- function sht3x_is_measuring is now private and only for internal use,
user task has always to use function vTaskDelay to wait for
measurement results
- function sht3x_is_measuring was simplified and returns now just a
boolean value
- private function sht3x_reset added which is used to reset the sensor
during initialization
- active flag in sensor data structure not needed anymore
- function sht3_get_raw_data simplified
- function sht3x_start_measurement returns now only a boolean
- function sht3x_start_measurement does not check anymore whether there is
already a measurment running
- new function sht3x_get_measurement_duration which returns the measurement
duration in ticks for configured repeatability
* SHT3x driver minor changes
- type sht3x_values_t replaced by separate float values
- additional repeatability parameter defined for function sht3x_start_measurement
- parameter of function sht3x_get_measurement_duration changed from
sht3x_sensort_t to sht3_repeat_t
- sensor modes and repeatability levels extended by prefix sht3x_
* SHT3x driver minor changes
- new high level function sht3x_measure added, it comprises all three
steps to perform one measurement in only one function
- example with two sensors removed
* SHT3x driver small correction
This patch gets the newlib standard stream descriptors playing well with the
lwip socket descriptors and the spiffs file descriptors. The LWIP_SOCKET_OFFSET
is now defined to be 3, rather than zero, to avoid clashing with the standard
stream descriptors, and the SPIFFS_FILEHDL_OFFSET is bumped up to start after
the lwip descriptors.
* bmp180: comment typo
* ds3231: minor code style fixes. Comment, on the week day start.
* Reverse engineered ets_timers.o Switch from FreeRTOS queue to task notification. Removed unknown/unused code. Rename sdk_ets_handler_isr to process_pending_timers. Add function for microseconds Simplify time to ticks conversion
* ets_timer: code for using the FreeRTOS timers, and remove from libs.
* libc: update to a recent newlib version.
* LwIP v2 support
* spi_write: use uint32_t for the page iteration counter. The page counter was using an uint8_t which seems unnecessary and might wrap.
* sysparam_get_bool: memcpy the binary values out.
* FreeRTOS 9.0.1
* Add an argument to ISRs. Disable interrupts while masking them.
* sysparam: reserve one more flash sector before placing the sysparams. This is to help work with recent SDKs that add a RF cal sector by default in the fifth last sector - just so the sysparam sectors do not jump around when using different SDK versions.
* upnp example: strip down the lwipopts.h file
* sysparam editor: accept newline to end a line of input.
* Add Wificfg. Uses the sysparam store to save the wifi configuration. Adds a basic http server for configuration.
* lwip: disable the tcpip_core_locking_input option. With this option enabled some lwip input processing occurs in the pp task which works well for some uses but some code uses a lot of stack (e.g. mdns) and will overflow the pp task stask, or might unnecessarily slow the critical pp task,
so disable this by default and if not already defined.
* sdk_cnx_add_rc: fix overflow of the table, when no match is found. Also adds source code for sdk_cnx_rc_search, adding a null pointer dereference. Check (that is not expected to be seen), and source code for sdk_cnx_remove_rc.
* http_get example: fix compilation with ipv6 disabled.
* lwip: update to master branch.
* wificfg: allow the AP channel to be 1.
* lwip: rework the tcp ooseq handling. It now accounts for the number of rx pool buffers used and the
available memory when deciding the number of ooseq buffers to retain. Enable the TCP Selective ACK support which appears to help a lot on lossy wifi when using the OOSEQ option.
* Update lwip, fixes losses of pcbs and associated problems.
* lwip: revise the tcp ooseq limit calulations. Was making a mess of the calculation sign. Also added a COPY_PP_RX_PBUFS define to include appropriate limits for this option.
* lwip: ooseq_max_bytes() - set a practical target memory size.
* lwip: revise ooseq handling. Modified for lwip backwards compatibility based on upstream feedback.
* lwip: update to the 2.0.3 release
* lwip: merge upstream master.
* libc: update to upstream master.
* lwip: fix building without TCP_QUEUE_OOSEQ
This is to help work with recent SDKs that add a RF cal sector by
default in the fifth last sector - just so the sysparam sectors do not
jump around when using different SDK versions.
* Get testing system by projectgus working with master HEAD
* Fix running dual test. Add basic wifi test
* Moved spiff test to a test case. Reset retries in test runner
* Add timers test case
* test_runner: List test cases and run individual test cases
* Add README for tests
* Update README.md
* Code clean-up
* Python3.4 support. README.md update
