- implemented SYS_DRVINFO syscall and version handling for the semihosting driver
- removed a support of old oocd versions
renamed kconfig options:
- CONFIG_SEMIHOSTFS_HOST_PATH_MAX_LEN to CONFIG_VFS_SEMIHOSTFS_HOST_PATH_MAX_LEN
- CONFIG_SEMIHOSTFS_MAX_MOUNT_POINTS to CONFIG_VFS_SEMIHOSTFS_MAX_MOUNT_POINTS
CONFIG_VFS_SUPPORT_IO: for basic I/O functions support
CONFIG_VFS_SUPPORT_DIR: for file/directory functions support
CONFIG_VFS_SUPPORT_SELECT: for select support
1. The translation should be first reviewed by technical reviewers;
2. and then by language reviewers.

!4452 used setting LINK_LIBRARIES and INTERFACE_LINK_LIBRARIES to link
components built under ESP-IDF build system. However, LINK_LIBRARIES does
not produce behavior same as linking PRIVATE. This MR uses the new
signature for target_link_libraries directly instead. This also moves
setting dependencies during component registration rather than after all
components have been processed.
The consequence is that internally, components have to use the new
signature form as well. This does not affect linking the components to
external targets, such as with idf_as_lib example. This only affects
linking additional libraries to ESP-IDF libraries outside component processing (after
idf_build_process), which is not even possible for CMake<v3.13 as
target_link_libraries is not valid for targets not created in current
directory. See https://cmake.org/cmake/help/v3.13/policy/CMP0079.html#policy:CMP0079
Using xxx_periph.h in whole IDF instead of xxx_reg.h, xxx_struct.h, xxx_channel.h ... .
Cleaned up header files from unnecessary headers (releated to soc/... headers).
Removes the need to know/guess the paths to these libraries. Once we are gcc 8 only, we
can remove -nostdlib and no additional arguments are needed for system libraries.
The catch is: any time IDF overrides a symbol in the toolchain sysroot, we need
an undefined linker marker to make sure this symbol is seen by linker.
