Before:
The cache won't be disabled when XIP on psram. But during flash
erasing/programming, read data will be courrupt.
When XIP in psram is enabled, the image is not mapped to the cache so
usually there will be no flash access. The only way to read from flash
is via the driver or use mmap. The driver has protection during erasing,
while th mmap region not.
Now:
Mmap APIs provide a flag to make mmap->unmap region mutually exclusive
to flash erase/programming when XIP from psram. SPI Flash write APIs
will benefit from this. When the flag is used, no concurrent access to
mapped region will happen while writing; otherwise the cache will be
disable to avoid data corruption.
Most ESP-IDF APIs calls mmap with this flag. As for users calling
mmap-like APIs directly, they can choose whether to enable this by a
flag.

ESP_FAULT_ASSERT(C) was silently deleted by the optimizer when C is a cached
flag/status already proven by a preceding `if (!C) return/goto`: the compiler
folds C to a constant and drops all three checks, removing the fault-injection
protection with no warning.
Add a test app that verifies PLACE_IN_SECTION, _SECTION_ATTR_SYMBOL_DECL_GENERIC,
_SECTION_START and _SECTION_END macros work correctly on Linux.
The test places 5 uint32_t values into a custom .test_data_table section from
two separate translation units, then iterates the section at runtime to verify
the correct count and content of all entries.
Includes:
- Custom linker script (ld/test_section.ld)
- Build-test-rules entry (linux only)
- pytest host_test marker
Add PLACE_IN_SECTION, _SECTION_ATTR_IMPL_GENERIC, _SECTION_ATTR_SYMBOL_DECL_GENERIC,
_SECTION_START and _SECTION_END macros that emit real section attributes on every
platform (embedded ELF, Linux ELF, macOS Mach-O).
Unlike _SECTION_ATTR_IMPL which is a no-op on Linux, these macros work uniformly
across all targets, enabling link-time arrays for error-code tables, init-function
arrays, and similar patterns.
Also moves _COUNTER_STRINGIFY definition before its first use.
In commit a0bcffcc, some ESP_RETURN and ESP_GOTO debug macros were
introduced. But this caused a regression with CONFIG_COMPILER_OPTIMIZATION_CHECKS_SILENT
case. Its better to move this macros to HTTP client component itself, as
the debug log is still desired for the specific use-case.
This commit replace macro MEM_CHECK with return on failure and
updated usage of reespctive APIs' in IDF.
This also update th prototype of API esp_http_client_add_auth().

__VA_NARG__ is copied from a forum post and is a pretty common implementation
with a high chance of causing naming collision
Added ESP_ namespace to avoid this.

fix(ll): remove FLAG_ATTR macro
Such kind of operator overload will not work because C++ thinks such overload is ambiguous and it still prefer the built-in one which accepts and returns integer. Manually force type conversion seems to be unavoidable.
