build system: remove lwip from common requirements
lwip was added to common requirements list to provide "sys/socket.h"
header to all components without additional requirements specified.

However, lwip pulls in a lot of dependencies on other components.
This commit removes lwip from common requirements to reduce the number
of components in G1-only apps.

To compensate for this removal, the following changes are made:
- newlib (which is a common requirement) has a public dependency on
  lwip if lwip is present in the build. This ensures that sys/socket.h
  is available as long as lwip component is included into the build.
- lwip is now a public requirement of esp-tls since esp_tls.h includes
  sys/socket.h header.
- lwip is now a public requirement o esp_http_client because
  sys/socket.h is included from esp_http_client.h
- lwip is now a private requirement of esp_wifi for "smartconfig_ack"
- lwip is now a private requirement of mqtt for socket functions
- lwip is now a public requirement of tcp_transport because
  esp_transport_tcp.h includes sys/socket.h header.
- mbedtls checks if lwip component is present in the build. If yes,
  net_sockets.c is added to the build, along with the dependency on
  lwip. Previously lwip was a public requirement of mbedtls
  unconditionally.

system/g1_components test app is updated to reflect the changes

Default public dependencies of a component before and after this
change, except common requirements:

- esp_timer (public dependency of freertos)
- bootloader_support (public dependency of esp_hw_support)
- vfs (public dependency of lwip)
- esp_wifi (public dependency of lwip)
- esp_event (public dependency of esp_wifi)
- esp_netif (public dependency of esp_event)
- esp_eth (public dependency of esp_netif)
- esp_phy (public dependency of esp_wifi)

After:

- esp_timer (public dependency of freertos)
- bootloader_support (public dependency of esp_hw_support)

Altogether, the following components have been always added as
public requirements to all other components, and are not added now
([breaking-change]):

- lwip
- vfs
- esp_wifi
- esp_event
- esp_netif
- esp_eth
- esp_phy

Application components now need to explicitly declare dependencies on
these components.

b7b9ea4361 newlib: add _RETARGETABLE_LOCKING support
This adds support for the retargetable locking implementation in
newlib 3. This feature will be enabled in the future toolchain builds.
With the present version of the toolchain, this code doesn't get used.

When _RETARGETABLE_LOCKING gets enabled, newlib locking implementation
will be modified as follows:

- Legacy ESP-specific _lock_xxx functions are preserved. This is done
  because ROM copies of newlib in ESP32 and ESP32-S2 rely on these
  functions through the function pointer table. Also there is some
  code in IDF which still uses these locking functions.

- New __retarget_lock_xxx functions are introduced. Newlib expects
  these functions to be provided by the system. These functions work
  pretty much the same way as the ESP-specific _lock_xxx functions,
  except one major difference: _lock_acquire receives the lock pointer
  by value, and as such doesn't support lazy initialization.

- Static locks used by newlib are now explicitly initialized at
  startup. Since it is unlikely that these static locks are used at
  the same time, all compatible locks are set to point to the same
  mutex. This saves a bit of RAM. Note that there are still many locks
  not initialized statically, in particular those inside FILE
  structures.

346cf4430d esp_system: introduce system time functions

cc1d287133 newlib: use --specs=nano.specs to enable "nano" version of C library
esp2020r1 toolchain includes a nano.specs file, which instructs GCC to
substitute libc.a with libc_nano.a.

In the build system, this simplifies handling of the nano formatting
option, eliminating LIBC and LIBM global variables.

9b350f9ecc cmake: some formatting fixes
Do not include bootloader in flash target when secure boot is enabled.
Emit signing warning on all cases where signed apps are enabled (secure
boot and signed images)
Follow convention of capital letters for SECURE_BOOT_SIGNING_KEY
variable, since it is
relevant to other components, not just bootloader.
Pass signing key and verification key via config, not requiring
bootloader to know parent app dir.
Misc. variables name corrections

3882e48e8a cmake: use new signature form of target_link_library to link components
 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

22514c1dd9 cmake: For gcc8 use linker to find paths to libc, libm, libstdc++, etc
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.

562af8f65e global: move the soc component out of the common list
This MR removes the common dependency from every IDF components to the SOC component.

Currently, in the ``idf_functions.cmake`` script, we include the header path of SOC component by default for all components.
But for better code organization (or maybe also benifits to the compiling speed), we may remove the dependency to SOC components for most components except the driver and kernel related components.

In CMAKE, we have two kinds of header visibilities (set by include path visibility):

(Assume component A --(depends on)--> B, B is the current component)

1. public (``COMPONENT_ADD_INCLUDEDIRS``): means this path is visible to other depending components (A) (visible to A and B)
2. private (``COMPONENT_PRIV_INCLUDEDIRS``): means this path is only visible to source files inside the component (visible to B only)

and we have two kinds of depending ways:

(Assume component A --(depends on)--> B --(depends on)--> C, B is the current component)

1. public (```COMPONENT_REQUIRES```): means B can access to public include path of C. All other components rely on you (A) will also be available for the public headers. (visible to A, B)
2. private (``COMPONENT_PRIV_REQUIRES``): means B can access to public include path of C, but don't propagate this relation to other components (A). (visible to B)

1. remove the common requirement in ``idf_functions.cmake``, this makes the SOC components invisible to all other components by default.
2. if a component (for example, DRIVER) really needs the dependency to SOC, add a private dependency to SOC for it.
3. some other components that don't really depends on the SOC may still meet some errors saying "can't find header soc/...", this is because it's depended component (DRIVER) incorrectly include the header of SOC in its public headers. Moving all this kind of #include into source files, or private headers
4. Fix the include requirements for some file which miss sufficient #include directives. (Previously they include some headers by the long long long header include link)

This is a breaking change. Previous code may depends on the long include chain.
You may need to include the following headers for some files after this commit:

- soc/soc.h
- soc/soc_memory_layout.h
- driver/gpio.h
- esp_sleep.h

The major broken include chain includes:

1. esp_system.h no longer includes esp_sleep.h. The latter includes driver/gpio.h and driver/touch_pad.h.
2. ets_sys.h no longer includes soc/soc.h
3. freertos/portmacro.h no longer includes soc/soc_memory_layout.h

some peripheral headers no longer includes their hw related headers, e.g. rom/gpio.h no longer includes soc/gpio_pins.h and soc/gpio_reg.h
