edit/editcmd.c

* changed searching algorithm of 'TAGS' file
 * changed #include "etags.h" to "../edit/etags.h" for building outside of sources tree
edit/etags.c:
 * apply template from maint/template.c file
 * rename all functions with prefix etags_*
 * make function "etags_get_pos_from" in file-scope visibility
edit/etags.h:
 * added logic block "#ifndef ... #define ... #endif" for correctly processing of header file
 * remove declaration of file-scope function etags_get_pos_from (ex. get_pos_from)
