a5f96b22d1 examples/sdmmc: enable internal pull-ups in SD mode
Some development boards do not have sufficient external pull-ups on
SD card pins. Most notably, if high level on GPIO13 is not registered
by the card when GO_IDLE_STATE command is received, the card will enter
SPI mode and further communication will not be possible, until power to
the card is toggled.

This change enables internal pull-ups on SD card pins in an attempt to
make this initialization process more reliable.

821c70f5d7 examples: Standardise naming of files, symbols, etc. in examples
* Use "example" in all example function & variable names,
  ie use i2c_example_xxx instead of i2c_xxx for example functions.
  Closes #198 https://github.com/espressif/esp-idf/issues/198
* Mark example functions, etc. static
* Replace uses of "test" & "demo" with "example"
* Split the UART example into two
* Rename "main" example files to end with "_main.c" for disambiguation

5ea9097dbd esptool: Update to latest v2.0 beta version
* New "espefuse.py set_flash_voltage" command to easily set a fix
  VDD_SDIO regulator voltage (1.8V, 3.3V or disabled).
* Fixes bugs when flashing files with non-4-byte aligned lengths
  (doesn't effect esp-idf image files)
* README improvements
