3b9cb25fe1
Added a new structure esp_app_desc_t. It has info about firmware: version, secure_version, project_name, time/date build and IDF version. Added the ability to add a custom structure with a description of the firmware. The esp_app_desc_t is located in fixed place in start of ROM secotor. It is located after structures esp_image_header_t and esp_image_segment_header_t. app_version is filed from PROJECT_VER variable (if set in custom make file) or PROJECT_PATH/version.txt or git repo (git describe). Add API to get app_desc from partition.
