In some cases, deleting a folder will return unexpected results. For example, ENOENT should be returned when deleting a non-existent folder, but the result will return ENOTDIR.
Fix icmpv6_reply logic broken by commit 48311cc61f and 391b501639.
- 48311cc61f "Fix unaligned memory access when creating ICMP Port Unreachable messages"
- It removed `htonl` function outside `data`, then the byte order may be wrong, so add `htons` back.
- 391b501639 "net: extract l3 header build code into new functions"
- It mis-removed the `memmove`, and the icmpv6 has no payload copied after this commit.

Set IPv4 flag before processing ipforward, otherwise the ICMP packet responded by ipforward may sometimes be regarded as IPv6.

* enable DLFCN.
* bump WAMR to a version which i happened to test.
* enable bulk-memory because it's required by recent versions of
wasi-sdk, which i happened to use to build a test module.
(test.wasm in the log below.)
Lightly tested with a stripped down version of WAMR native-lib example. [1]

cookie->result, then this return value can be returned to the
application;
2. rpmsgdev seek: the type "off_t" may be 64bit, so modify the offset
in "struct rpmsgdev_lseek" to int64_t too;
3. rpmsgdev_seek: the rpmsgdev_seek in client should update the

Fix build break on thumb2 mode:
opus/celt/arm/celt_pitch_xcorr_arm-gnu.S: Assembler messages:
opus/celt/arm/celt_pitch_xcorr_arm-gnu.S:146: Error: thumb conditional instruction should be in IT block -- `movle pc,lr'
Reference:
https://developer.arm.com/documentation/100067/0612/armclang-Command-line-Options/-mimplicit-it
In A32 code, the integrated assembler accepts all conditional instructions
without giving an error or warning. In T32 code, the integrated assembler
outputs an implicit IT block when there is a conditional instruction
without an enclosing IT block. The integrated assembler does not give an
error or warning about this.

The option '-mthumb' is only valid for C source files and it is not passed to the assembler.
If 'thumb' is not considered in some assembly projects, the system will generate
'undefined instructions' when running incompatible instruction:
arm_undefinedinsn: Undefined instruction at 0x380cfc98
This assembly file should be compiled with .thumb but it doesn't:
380cfc90 <hobot_i8_i32_gemm_nn_m4_n8_neon>:
380cfc90: e92d4ff0 push {r4, r5, r6, r7, r8, r9, sl, fp, lr}

This commit will enable the thumb option of the assembly file by default,
so that when compiling the assembly file, the machine code and the system will be in a consistent state.
----------------------------------------------------------------

GCC Manual:
-mthumb
Generate code for the Thumb instruction set. The default is to use the 32-bit ARM
instruction set. This option automatically enables either 16-bit Thumb-1 or mixed 16/32-bit
Thumb-2 instructions based on the -mcpu=name and -march=name options.
** This option is not passed to the assembler. **
** If you want to force assembler files to be interpreted as Thumb code,
either add a `.thumb' directive to the source or pass the -mthumb option
directly to the assembler by prefixing it with -Wa. **

* disable too verbose wamr options.
* enable CONFIG_SCHED_WAITPID. because async execution on nsh prompt
sometimes confuses me.
* enable toywasm. it's sometimes convenient to have another interpreter.

Split out ipv4_nat_in/outbound_internal which returns entry instead of error code, for later ICMP error types, does not change any current logic.
Reason: Outer packet doesn't have information of port, so we need to find entry by inner packet, and apply the entry to outer packet.
| Outer Packet: SRC = Peer IP<No Port>, DST = External IP<No Port> |
| Inner Packet: SRC = External IP:Port, DST = Peer IP:Port |

This commit is for later ICMP error types processing, and does not change any current logic.
Reason for supporting both side of modification is that an inbound ICMP Error MSG may carry original packet like this:
| IP HDR: SRC = Peer IP, DST = External IP |
| ICMP HDR: ERROR MSG |
| <Origin> IP HDR: SRC = External IP, DST = Peer IP |
| <Origin> L4 HDR: SRC = External Port, DST = Peer Port |
So we need to support inbound translation (External -> Local) on SRC or DST of each header.
And so do the outbound direction.
