bf91047f33 libc: Fix getrandom() bug: Didn't propagate read error 
* libs/libc/misc/lib_getrandom.c, in function getrandom():
  We were assigning the return value of _NX_READ() to nbytes, a
  variable of the unsigned type size_t. Note that _NX_READ() resolves
  to either read() or nx_read(), both of which return the signed type
  ssize_t to indicate either the number of bytes read successfully
  (>= 0) or an error (< 0). Then we were testing for a negative
  size_t value, a condition that can never occur. The end result is
  that if an error occured in _NX_READ(), it would never be detected
  and getrandom() would return some large positive value. This bug is
  corrected by assigning the return value of _NX_READ() to a new local
  variable, ret, of size ssize_t.

9288ed85e7 RISC-V: Add/fix implementation for arch_elf.c 
The jump instruction relocation had an assert that tests for jumps with
an offset of 0. This makes it so that a while(1); statement causes an
assert because the jump instruction points to the same address, which
is perfectly legal.

Addend was not handled correctly in several reloc types.

Add ADD32/64 + SUB32/64 relocations, for some reason the compiler
I use likes to add them.

fbf05db906 fix up_tls_info define for BUILD_KERNEL 
Summary:
- In case of BUILD_KERNEL, NuttX uses USR mode sp and SVC mode sp.
- The kernel runs on SVC mode sp.
- While the kernel is running, up_getsp() cannot get the TLS address.
- The kernel requires tls_get_info() function.
- For the user land, up_getsp() can be used.
- tls_getinfo.c is always compiled and tls_get_info() function is
  filtered by macros in the tls_getinfo.c.

Impact:
BUILD_KERNEL

31ffa6d576 libdsp/lib_observer.c: remove dir argument from speed observers 
We can automatically detect the direction of movement from angle diff

01cbe9133e libdsp/lib_observer.c: update some comments 
The angle observer always refer to a motor electrical angle,
while the speed observer can be applied to a motor electrical speed or a motor mechanical speed.

raiden00pl
26f1be27dd libdsp/lib_observer.c: separate angle observer from speed observer 
They can be used completely independently, so they should'n be coupled.
For example, a sensored motor controller in speed control mode doesn't need an angle estimator.

b859f2750b libc/math: fix log and logf calculations on ARMv7 (and maybe others) 
Probably this is a bug of a GCC, but on AMRv7 the code "if (relax_factor > 1)"
generates "bne.n" instruction if "relax_factor" is "int". Few lines above
"relax_factor *= LOG_RELAX_MULTIPLIER;" is done without overflow check hence
at some moment overflow occurs and "relax_factor" becomes a zero and condition
"if (relax_factor > 1)" becomes always evaluated to "true" hence "epsilon"
becomes zero always.

Probably this is not the best way to fix the bug (The best way is to report it
to GCC), but this change allows to get correct behavior of "log" and "logf" for
ARMv7 based MCUs
